blank line in letter address causes failure

[pelle@…]

Hi,

According to Debian #271233, empty lines in the address field in letters
causes a latex error. It says "LaTeX Error: There's no line here to end.". The
attached sample file provided by the reporter illustrates the problem. I have
verified that the bug still exists in LyX 1.5.1.

This a limitation of LaTeX's standard letter class.

To avoid this, you can add this as ERT to the empty line:
\hspace*{0pt}
(see the attachment)

There is not much we can do here, for proper layouted letters you can use one of
the various other letter classes LyX provides.

Of course something could (and should) be done. As a user I expect that a
document without dirty tricks (i.e. ERT) does not lead to a LaTeX Error. If it
does, then the software is crap.
Therefore it should either be impossible to enter such empty lines, or the
created LaTeX should be modified so that it works.

[Uwe Stöhr]

You convinced me.

Presumably, the solution will have to involve an indication in the layout files
of where you can have blank lines and where you can't.
