Hi there,
I was trying to Change some icons in the images dir and found a way to
crash emacs. It is 100% reproducible. Tested in GNU Emacs 23.0.0.6
(i686-pc-linux-gnu, GTK+ Version 2.8.20) of 2006-11-01.
Steps to reproduce:
1.Backup:
etc/images/gnus/toggle-subscription.xpm
etc/images/mail/save.xpm
etc/images/mail/save-draft.xpm
2.Create empty files:
etc/images/gnus/toggle-subscription.xpm
etc/images/mail/save.xpm
etc/images/mail/save-draft.xpm
3. M-x gnus
4. C-x 5 b *Group* RET
5. Crash
Backtrace:
DISPLAY = :0.0
TERM = xterm
