            Bug ID: 295726
          Severity: crash
           Version: unspecified
          Priority: NOR
          Assignee: kdepim-bugs at kde.org
           Summary: kmail crashes every now and then during checking mails
    Classification: Unclassified
                OS: Linux
          Reporter: rydberg at o2.pl
          Hardware: Ubuntu Packages
            Status: UNCONFIRMED
         Component: general
           Product: kontact

Application: kontact (4.8.0)
KDE Platform Version: 4.8.1 (4.8.1)
Qt Version: 4.8.0
Operating System: Linux 3.0.0-16-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
I was checking and sorting my mail. Every couple e-mails kmail crashes without
any apparent reason: no matter if an email was in a plain text or html, had an
attachement or not

The crash can be reproduced every time.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
