Re: Reproducible gtk crash

[Simon Josefsson]

I get a different back trace from each crash.  This is fresh CVS
(thanks to Stefan and Luc for making CVS build again) with CFLAGS=-g.
Below is a few runs of emacs under gdb.  It is completely
reproducible.  I suspect some Debian GTK/Gnome package update...

Any ideas?  Thanks.
