Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.
Your bug report will be posted to the bug-gnu-emacs@gnu.org mailing list,
and to the gnu.emacs.bug news group.
Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:
It was a bit hard to reproduce. In fact, I tried to make up a valid xbm
:data chunk, and failed (any hints for a working example
appreciated...), because my Emacs crashed too often.
There are lots of ways to crash Emacs (just work with it for a while
while there are lots of broken xbm images in your buffer), but here is a
reproducable one:
- start emacs -Q
- run this in *scratch* buffer
(progn
(put-image '(image :type pbm :data "") 0)
(pop-to-buffer "*Messages*")
(goto-char (point-max)))
Now press <down> <right> <down> <right>.
When Emacs asks you whether you want to attach a debugger, answer
whatever you find appropriate :)
Sorry, no gdb available here, but I guess this is pretty reproducable
for those who have one.
