            Bug ID: 298570
          Severity: crash
           Version: 2.5.0
          Priority: NOR
          Assignee: digikam-devel at kde.org
           Summary: digikam crash
    Classification: Unclassified
                OS: Linux
          Reporter: ken_speakman at talk21.com
          Hardware: Ubuntu Packages
            Status: UNCONFIRMED
         Component: general
           Product: digikam

Application: digikam (2.5.0)
KDE Platform Version: 4.8.2 (4.8.2)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-23-generic-pae i686
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:
Starting digikam! The splash screen had almost finished.
This was just after booting. No other application had been started.
This is the second digikam crash - the first resulted ultimately in the
computer locking up, so I was unable to report the circumstances. The first
crash had occurred when I was updating timestamps of a batch of about 20
photographs.

-- Backtrace:
Application: digiKam (digikam), signal: Segmentation fault
Using host libthread_db library "/lib/i386-linux-gnu/libthread_db.so.1".
