Hey! You found a bug from my crash :-) After you fixed the bug my crash
was fixed too.
I have a stock redhat 6.2 with helix-gnome updates. A large fraction of
our users have a similar system...
Anyway here is the stack trace from an extremely fresh gnome build. I'll
try a gtk build next. This crash occured on attempting to load a document
with tabs..
