Bug 335226

Application: digikam (3.5.0)
KDE Platform Version: 4.13.0
Qt Version: 4.8.6
Operating System: Linux 3.13.0-24-generic x86_64
Distribution: Ubuntu 14.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:

updating photo tags with digikam sorted by tags. I erased several empty tag categories, i selected another tag (on the right side menu) and waited while the "no active process" bar moved back and forth, then seleted another tag that I knew was populated with pictures. 
I'm playing musice from Amarok - from a samba mount where the uid's do not match - at the same time.
The Asus PC1215n laptop is on power, and the a vga monitor (1920x1080) is connected. I'm using the Nvidia ion proprietary drivers on a new install of kubuntu 14.04.

The crash can be reproduced sometimes.

-- Backtrace:
Application: digiKam (digikam), signal: Segmentation fault
