https://bugs.kde.org/show_bug.cgi?id=259951

           Summary: crash when asking to use untrusted SSL certificate
           Product: konversation
           Version: 1.3.1
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: konversation-devel at kde.org
        ReportedBy: thiago.bauermann at gmail.com


Application: konversation (1.3.1)
KDE Platform Version: 4.5.4 (KDE 4.5.4)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-23-generic i686
Distribution: Ubuntu 10.10

-- Information about the crash:
I connect to OFTC using SSL. The certificate is untrusted, so Konversation asks
whether I want to use it. I click on "Current session only". I noticed that
everytime I take a while (a few minutes) to answer that question, Konversation
crashes immediately. If I answer the question a few seconds after it shows up,
Konversation works as usual.

The crash can be reproduced some of the time.

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