Bug 375982

Application: digikam (4.8.0)
KDE Platform Version: 4.14.5
Qt Version: 4.8.6
Operating System: Linux 4.4.39-desktop-1.mga5 x86_64
Distribution: "Mageia 5"

-- Information about the crash:
- What I was doing when the application crashed: Just launching the application after Mageia 5.1 reinstall without any modification to /home directory.
Same problem with Amarok, The other applications are OK and the database is OK (phpmyadmin analysis).

The crash can be reproduced every time.

-- Backtrace:
Application: digiKam (digikam), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
