Application: gwenview (2.8.4)
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.2
Operating System: Linux 3.2.0-4-amd64 x86_64
Distribution: Debian GNU/Linux 7.0 (wheezy)

-- Information about the crash:
- What I was doing when the application crashed:
Closed Gwenview window when it was showing thumbnails in a directory (527 files).

- Custom settings of the application:
~/.thumbnails and ~/.cache/thumbnails are symlinks to /dev/null if that makes any difference.

The crash can be reproduced some of the time.

-- Backtrace:
Application: Gwenview (gwenview), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
