           Summary: Digikam crash at startup (due to notification window)
           Product: digikam
           Version: unspecified
          Platform: Fedora RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: digikam-devel at kde.org
        ReportedBy: fredericg_99 at yahoo.fr


Application: digikam (2.6.0-beta2)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.8.0
Operating System: Linux 3.2.7-1.fc16.x86_64 x86_64
Distribution (Platform): Fedora RPMs

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

According to the trace, the crash is related to the notification window.
I may add that I am quite "frenetic" with my desktop (Gnome 3), and the crash
seems to occur when I start digikam, then immediately do something else.
If I wait for digikam to start, then for the task that scan new items to finish
properly, nothing bad happens.

The crash can be reproduced some of the time.

-- Backtrace:
Application: digiKam (digikam), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
