            Bug ID: 339593
           Summary: Crash on opening
           Product: digikam
           Version: unspecified
          Platform: Ubuntu Packages
                OS: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: digikam-devel at kde.org
          Reporter: s2g9h+ennz3zdcrvs88 at sharklasers.com

Directly after opening, Digikam shows thumb previews for up to 5 seconds then
crashes. Crash log below. If there's way I can make a more verbose output,
please reply to this bug report so I can do that. I checked the sqlite db and
it doesn't seem corrupt.
