            Bug ID: 342985
           Summary: KTP Contact List crashes when attempting to join a
                    chat room
           Product: telepathy
           Version: git-latest
          Platform: Gentoo Packages
                OS: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: common-internals
          Assignee: kde-telepathy-bugs at kde.org
          Reporter: dan at redchops.com

I initially thought this was an issue with ktp-contact-list, however the stack
trace showed differently. Signed in to a Jabber account, when I try to join a
chat room the contact list window simply vanishes without any sort of crash
logger appearing. Running ktp-contactlist through gdb, I see that it generates
a stack trace, below. 

Reproducible: Always
