           Summary: Crash when MSN contact disconnects
           Product: kopete
           Version: 1.0.0
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kopete-bugs at kde.org
        ReportedBy: ninja at slaphack.com


Application: kopete (1.0.0)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-26-generic x86_64
Distribution: Ubuntu 10.04.1 LTS

-- Information about the crash:
I have an MSN contact who's on a flaky wireless connection. It's difficult to
confirm that this happens every time, but it seems whenever his connection
drops, I crash.

This doesn't seem to happen when people go on or offline normally, and it only
seems to be happening with this one contact.

The crash can be reproduced some of the time.

 -- Backtrace:
Application: Kopete (kopete), signal: Segmentation fault
