           Summary: Kontact Crash
           Product: kontact
           Version: 4.4.10
          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 (4.4.10)
KDE Platform Version: 4.6.3 (4.6.3)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-8-generic i686
Distribution: Ubuntu 11.04

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

Kontact (KMail view) was running as a inactive window without any activity,
i.e., no mail was being fetched in the background. The active window of Firefox
was partly overlapping the Kontact window. Kontact crashed when I clicked on
the inactive Kontakt window to transfer the focus from Firefox to Kontact. It's
hard to reproduce but happened more than once.

Since this happens only on a new laptop, desktops effects were disabled due to
minimize problems related to driver instability. Related output from lspci:
