           Summary: Kontact crash when switching to (inactive) window
           Product: kontact
           Version: unspecified
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: georg.wittenburg at gmx.net


Application: kontact (4.7.0 )
KDE Platform Version: 4.7.00 (4.7.0)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-10-generic i686
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:

Kontact crashed when I switched to the Kontact window, which had finished
checking mails in the background, by clicking on it (a Firefox window was
active before the switch). Kontact was displaying the summary view at the tiem.

The crash can be reproduced some of the time.
