Bug 341529

Application: digikam (4.0.0)
KDE Platform Version: 4.14.2
Qt Version: 4.8.6
Operating System: Linux 3.13.0-40-generic x86_64
Distribution: Ubuntu 14.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:
"Advanced slideshow", after a few seconds, the program crashes. Happens each time, with various settings (fade out, or no transisiton effect, 8 seconds, or 2 seconds on each photo...)
It does not happen however if I launch the diaporama directly (not "advanced")

The crash can be reproduced every time.

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