[Bug 44991] xchat-gnome segfaults on startup

[Marius Gedminas]

Public bug reported:

Since today I am unable to start xchat gnome.  It segfaults on startup:

$ gdb xchat-gnome

I see /usr/lib/libsexy.so.2 in the stack trace, and I notice that I've
upgraded libsexy2 to version 0.1.7-0ubuntu5 last night.  Could that be
the cause?
