Bug 339650

Selected a different thumbnail in album preview mode (line of thumbnails on top, larger preview of selected pic.  below). Pics where mostly RAW files (Fuji RAF).
This does not happen every time.

Digikam was compiled from tar file.


Reproducible: Always

Steps to Reproduce:
1. select thumbnail
2. select a different thumbnail
now digikam sometimes crashes



Digikam was compiled from tar file. System is Linux, Ubuntu 14.04 
KDE Components use repos from Kubuntu backport and ppa.launchpad.net/philip5/kubuntu-backports/ubuntu
