Application: gwenview (2.8.3)
KDE Platform Version: 4.8.3 (4.8.3)
Qt Version: 4.8.2
Operating System: Linux 3.4.3-1.fc17.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
I was organizing files in a samba share with Gwenview which I had opened from Nautilus, thus the folder I was working in was ~/.gvfs/share.

When I deleted an empty directory in a writable share, Gwenview crashed.

The crash can be reproduced some of the time.

-- Backtrace:
Application: Gwenview (gwenview), signal: Segmentation fault
