lyx: SIGSEGV signal caught - can't launch LyX anymore

[pbinetti@…]

Hello,

I ran into this problem for the first time today (2008 May 7). I've been using
my lyx version for long, but always worked OK. I could not find any bug on that
already reported.
I call the severity of this problem critical, although it's catastrophic for me:
I just can't launch LyX.

Following, the relative information. If you need more, don't hesitate to ask.

My LyX problem:

pietro@t42-ibm:phd_thesis$ lyx
QPaintEngine::setSystemClip: Should not be changed while engine is active
QPaintEngine::setSystemClip: Should not be changed while engine is active
QWidgetPrivate::beginSharedPainter: Painter is already active

lyx: SIGSEGV signal caught
Sorry, you have found a bug in LyX. Please read the bug-reporting instructions
in Help->Introduction and send us a bug report, if necessary. Thanks !
Bye.

Is it possible that you updated qt or glibc or something, and that your LyX
version is compiled against some old libraries?

Hi,

Well, I update my debian-lenny almost every day. However, I
tried to remove the lyx package and reinstall it again, but I get the
same error.

Or I should do something different?

You reported the bug, or are watching the reporter.

[Juergen Spitzmueller]

which version of qt do you have installed?

Can you build the sources yourself?

I have qt4 installed. In my repositories of the debian package manager I
don't see the qt4 source, at a first glance. But I can always find that
source code and recompile it myself, if necessary.

Is that the way to go? It's still not clear to me, why lyx doesn't work
if I remove the package from my system and install it again from
scratch...

[Juergen Spitzmueller]

I suspect that the lyx binary you use does not match the libraries on your
system. If so, this is an issue of your distribution.

If you can build lyx from scratch, such problems would be excluded.

However, my question about qt was if you use qt 4.4 (not qt4 in general). There
are known problems with LyX and qt 4.4 that have been resolved for forthcoming
LyX 1.5.5.

I also filed a bug in kubuntu and it seems that incompatibility with new
version of qt4 is the problem

​https://bugs.launchpad.net/ubuntu/+source/lyx/+bug/228067

there is a possible solution proposed there removing new version of qt4.

[diabo@…]

I had the same problem when qt4 got updated to 4.4 yesterday. Solved it by
moving Trolltech.conf, just as for #4835
(#4819)

Hi,

Unfortunately, this doesn't halp in my case. After removing ~/.config/Trolltech.conf
and creating in again with qtconfig-qt4, lyx crashing exactly the same
way.

Hi,

Yes, it seems that's the bug I ran into. I checked, and qt4.4 is indeed
the version I have installed on my distribution (Debian Testing - Linux 2.6.24).

In the link you provide I see that the problem should be solved by
moving back to qt4.3. However, this is something I've never done: how
can I install a package (libqt4-core and libqt4-gui) at a version (4.3) older
than the one released in my distribution repositories (4.4)?

OK, the instability with qt 4.4 is a known bug that will be resolved in 1.5.5.

[mfg@…]

It is mentioned that version 1.5.5 will solve but ...
WE NEED TO WORK IN THE MEANWHILE!

please do not mark as resolved.- reopen bug please!!

Is there a way to batch process files from lyx to latex?
in command line so that we can work with kile or another processor.

I am now very worried with lyx since this issue proves that the processor is
very vulnerable and leaves us users in the dark. For future releases: Is it
possible for lyx to use .tex files as default rather than .lyx so that in a
similar failure users can continue working.

[Juergen Spitzmueller]

LyX 1.5.5 will be released in a few days.

In the meantime, you can use the debian unstable version of LyX 1.5.4, which
apparently includes the fix:

​http://packages.debian.org/sid/i386/lyx/download

The command to export LyX files to latex is "lyx -e latex file.lyx"

And please don't shout. I am aware that this is frustrating, but everybody here
is doing his best (the failure, btw, is on the side of your distributor).

[mfg@…]

command line is most useful, thank you.

version 1.5.4 does not solve the bug, see
​https://bugs.launchpad.net/ubuntu/+source/lyx/+bug/228067

please realize that from the user side the bug is NOT resolved fixed.

[Juergen Spitzmueller]

This bug tracker indicates the status of the bugs in the current development
cycle.

This bug is (fortunately) fixed in what becomes 1.5.5, that's why it is marked
FIXED. Note the "Target Milestone". It indicates to both the developers and the
users that the bug is resolved as of the indicated version.

Note that this bug has the highest priority for us, and we try to get out 1.5.5
as soon as possible.

Did you really try the 1.5.4 version from _debian unstable_ (sid) I referred
to? People affected by this bug have reported that this version does not crash.

[mfg@…]

I just tried to install 1.5.4 version from _debian unstable_ (sid)
However, the package installer (Gdebi) returns
"Error:Dependency not satisfiable:
libboost-filesystem1.34.1

However, checked with adept and libboost-filesystem1.34.1 is installed

when is 1.5.5 expected?

[Juergen Spitzmueller]

when is 1.5.5 expected?

Next Monday (May 12).

excelent!

I shall live without lyx till monday.

keep the good work, congratulations!

I also tried it with

I run xubuntu 8.04.

Finally I used "alien lyx-1.5.5-1_openSuse10-3.i586.rpm"
and then "dpkg -i lyx_1.5.5-2_i386.deb"
So lyx was installed and is working fine. No crashes when opening or compiling
lyx files.

Martin, do you have the qt4 header files (named qt4-devel on most distros)
files installed?

yes, "libqt4-dev" - Qt 4 development files - are installed.

Regarding comment 17:

This bug is (fortunately) fixed in what becomes 1.5.5, that's why it is marked
FIXED. Note the "Target Milestone". It indicates to both the developers and the
users that the bug is resolved as of the indicated version.

Juergen, I suggest that you create a keyword "fixedinbranch" and use that instead
of closing bugs. The bugs could then be closed when the release is done.

It works perfectly except that to execute it under Ubuntu 8.04 you
need to create a "lien" named libpcre.so.0 to libpcre.so.3

I also tried it with

"./configure --with-qt4-dir=/usr/lib/qt4". But same result,

I run xubuntu 8.04.
more info:

taram@marlux:~/Desktop$ uname -a
Linux marlux 2.6.24-16-generic #1 SMP Thu Apr 10 13:23:42 UTC 2008 i686 GNU/Linux

Finally I used "alien lyx-1.5.5-1_openSuse10-3.i586.rpm"
and then "dpkg -i lyx_1.5.5-2_i386.deb"
So lyx was installed and is working fine. No crashes when opening or compiling
lyx files.

I have introduced "fixedinbranch". This will hopefully limit confusion such as
Manuel's in the future.
