Application: dolphin (4.11.2)
KDE Platform Version: 4.11.2
Qt Version: 4.8.4
Operating System: Linux 3.11.0-11-generic x86_64
Distribution: Ubuntu Saucy Salamander (development branch)

-- Information about the crash:
- What I was doing when the application crashed:
On kde 4.11.2 (kubuntu)
Trash was empty.
In the /home/my_user/Downloads/ folder, tried to move to trash a .tgz file (44mb).
Result: Dolphin crashed and caused kwin to crash as well.
Kwin restarted, the file was in the trash can. So far, I cannot consistently reproduce this bug but it appears once in a while with no apparent reason.

If I recall correctly, I've been having this problem since KDE 4.10.
Feel free to contact me for further details.

Thanks!

The crash can be reproduced sometimes.
