Upper line of buttons in file open dialog disabled

[Jochen.Riehm@…]

Gentoo Linux, more details see below. This Bug is also reported as #189925
on Gentoo Linux, siehe URL.

When opening a file the directory select box does not allow to choose a
directoy. Also behind it are several buttons, all but one only showing when
mose is moved over them. They do not have any text and don't do anything.

The buttons "Documents" and "Examples" behind the above mentioned buttons work
as expected.

Reproducible: Always

Steps to Reproduce:

1. Open Lyx
2. Choose File/Open or click respective button
3. Try to change directory using the directory select box

Actual Results:
Items in directory select box are grayed out. Choosing one does not have any
effect.

Expected Results:
Items in directory select box are black. Choosing one displays content of
directory in main area of dialog box.

I'll try to give the relevant build information:

Re Comment 2:

Yes, I see the same problem. Also I see the repeated message

QPixmap::scaleWidth: Pixmap is a null pixmap

on sdtdout.

Thank you for your work!

This confirms that it is not a LyX bug. Sorry, but there's nothing we can
do about it.
