           Summary: Konversation crashes sometimes when marking something
           Product: konversation
           Version: unspecified
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: konversation-devel at kde.org
        ReportedBy: domo at no-limits-coaster.de


Application: konversation (1.3.1+ #4077)
KDE Platform Version: 4.4.92 (KDE 4.4.92 (KDE 4.5 RC2))
Qt Version: 4.7.0
Operating System: Linux 2.6.32-24ck-generic i686
Distribution: Ubuntu 10.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:

Sometimes, when I want to mark some texts in the chat view, Konversation
crashes instantly after I have finished marking. It doesn't happen really often
(about one time per day), but for me, it's quite annoying.

The crash can be reproduced some of the time.

-- Backtrace:
Application: Konversation (konversation), signal: Segmentation fault
