[Pkg-lyx-devel] Bug#597676: Export options vanish every other time

[Brendon Higgins]

Hi,

(Original reporter here.) I just tried with a clean ~/.lyx, and things seem to 
behave themselves. So there's something in my .lyx that lyx does not like. It 
turns out that it's certainly my preferences file. I narrowed it down after 
comparing the two folders recursively and moving things to the clean .lyx one 
by one.

I had a look at the settings for these formats, and noticed that "Document 
Format" is not ticked for them. If I change that for, say, "PDF (pdflatex)" so 
that it is ticked, then that particular option shows up in the Export menu all 
the time, as you ought to expect.

Before anyone shouts PEBKAC, while I did change the viewer application option 
(as you can tell), I don't believe I would have been silly enough to change 
that tick mark. I reckon, somehow, that property must have been either 
unchecked or not set by default properly when this property was introduced in 
an earlier version. (I've been using lyx on this machine since 2006, and would 
have had similar settings, using kghostview rather than okular.)

Anyway, I know how to work around it, now. Though it doesn't explain why LyX 
should start assuming the formats are document formats after it performs the 
reconfiguration (without altering the preferences).

Peace,
Brendon
