Bug 304412

Application: digikam (2.7.0)
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-29-generic-pae i686
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed: I tried to start an "Advanced Slideshow" with only 5 selected images (each of them is about 20 Mb in size), no transition effects, no soundtrack... the most basic.

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