            Bug ID: 329873
           Summary: crash during face detection 3.5
    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: karl-wilhelm at frommeyer.name

Application: digikam (3.5.0)
KDE Platform Version: 4.11.3
Qt Version: 4.8.4
Operating System: Linux 3.11.0-15-generic x86_64
Distribution: Ubuntu 13.10

-- Information about the crash:
- What I was doing when the application crashed:
I changed face attributes of jpg-files. After changing some 20 attributes all
cores were busy and swap utilisation increased.
I changed to folders to stop that, but swap increased and when reaching the
limit (10 GB) digikam crashed.

The crash can be reproduced sometimes.

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