[Bug 486240] [NEW] Lyx crashes with SIGSEGV when trying to show image

[nick]

Public bug reported:

Binary package hint: lyx

Lyx 1.6.2 crashes on showing image when "Scale on Screen (%)" option is
set to 50 and image size is 1266x421. Some other sizes cause chash too
(for example, 856x331), but setting scale to 51% solves the problem. In
9.10 this problem seems to be fixed, but 8.04 can also be affected.

It is quite simple to reproduce the bug: open gimp and create new empty
image with size 1266x421. Then start lyx and create new file. Choose
Insert->Graphics... and select your file. Go to "LaTeX and LyX options"
tab and set "Scale on Screen (%)" option to 50. Then push "Apply"
button. Lyx crashes with SIGSEGV signal.

I have several files with such "bad" image. LyX crashes always, when it
should show and image. Using vi to change lyxscale option in .lyx file
from 50 to 51 helps to workaround this problem. Image format seems to be
unrelevant, I had such bug with jpeg and png images.
