            Bug ID: 295857
          Severity: crash
           Version: unspecified
          Priority: NOR
          Assignee: kdepim-bugs at kde.org
           Summary: kontact crashes randomly in Kmail2
    Classification: Unclassified
                OS: Linux
          Reporter: upscope at nwi.net
          Hardware: openSUSE RPMs
            Status: UNCONFIRMED
         Component: general
           Product: kontact

Application: kontact (4.8.0)
KDE Platform Version: 4.8.1 (4.8.1) "release 481"
Qt Version: 4.8.0
Operating System: Linux 3.1.9-1.4-desktop x86_64
Distribution: "openSUSE 12.1 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
moving mouse between email in Kmail2 (in Kontact)

kmail-4.8.1-331.4.x86_64
kontact-4.8.1-331.4.x86_64


This repeats when it feels like. Cannot actually reproduce each time.  Tried
new test user and no crash occured under it. Going back to my user, it crashed
but no where near as frequent. 

May be related to nepomuk bug which I read has apatch coming.

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