            Bug ID: 335352
           Summary: Saving GPS correlation data lets Digikam hang in many
                    cases (KDE 4.13.1, Kubuntu 14.04).
    Classification: Unclassified
           Product: digikam
           Version: 3.5.0
          Platform: Ubuntu Packages
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: digikam-devel at kde.org
          Reporter: dreibh at iem.uni-due.de

Application: digikam (3.5.0)
KDE Platform Version: 4.13.1
Qt Version: 4.8.6
Operating System: Linux 3.13.0-24-generic x86_64
Distribution: Ubuntu 14.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:
Saving GPS correlation data lets Digikam hang in many cases (KDE 4.13.1,
Kubuntu 14.04). In order to create a stack trace, I killed the digikam process
with SIGSEGV. May be this helps debugging.

-- Backtrace:
Application: digiKam (digikam), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
