           Summary: digikam crashing while scanning >20000 pictures
           Product: digikam
           Version: 2.1.1
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: digikam-devel at kde.org
        ReportedBy: andreas.tarp at web.de


Application: digikam (2.1.1)
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-12-generic-pae i686
Distribution: Ubuntu 11.10

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

After storing more than 20k pictures in empty digikam picture folder I have
started digikam and initiated a scan for new pictures. At the beginning
everything went fine, one folder after another appeared. But after some time
digikam crashed. I have not done anything else in digikam in the meantime, I
was just waiting for digikam finishing the scan.

Hope this information is sufficient to find the bug causing digikam to crash.

BR, Andreas
