Application: dolphin (1.6.1)
KDE Platform Version: 4.6.4 (4.6.4)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-8-generic x86_64
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:
When opening dolphin and navigating in a directory full of pictures, dolphin crashes when it's loading the thumbnails (or before the tooltip appears when you hover the mouse over a picture).
It is not always happening but it is very frequent. It might be the first 3-4 times I will open a directory and then it's fine.

-- Backtrace:
Application: Dolphin (dolphin), signal: Aborted
