xchat-gnome crashed with SIGSEGV in g_closure_invoke()

[Thiago Figueiro]

Binary package hint: xchat-gnome

I noticed 102165 with the same title but since it is 3 years old I'm assuming mine is a new bug or a regression.

Steps to reproduce:

1. Open xchat
2. Connect to irc server
3. Join channel
4. crash

Confirming this. I had the same problem since Karmic.

How do I add debugging symbols to xchat? This stack trace isn't particularly helpful...

Confirmed this bug in 10.04 as well.
