           Summary: KMail locks up when displaying a message
           Product: kmail
           Version: unspecified
          Platform: Unlisted Binaries
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: cubranic at acm.org


Application that crashed: kmail
Version of the application: 1.12.2
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-16-generic i686

What I was doing when the application crashed:
When I advanced to the next message in my mailbox, KMail become completely
unresponsive and its CPU usage went to 100%. After about two minutes, I killed
it with a 'kill -HUP', which produced the attached stack dump.
