           Summary: KMail crashed while reading emails
           Product: kmail2
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: Linux
            Status: NEW
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: afiestas at kde.org


Application: kmail (4.9 pre)
KDE Platform Version: 4.8.00 (4.8.0) (Compiled from sources)
Qt Version: 4.8.0
Operating System: Linux 3.2.2-1-ARCH x86_64

-- Information about the crash:
Reading my kde-commits folders I was clicking "Next unread" quite quickly since
all the next commits were of no interest to me, after a few "next" it crashed.

I could reproduce it 4 times but is kinda random...

The crash can be reproduced some of the time.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
