Bug 291576

Application: dolphin (1.7)
KDE Platform Version: 4.7.3 (4.7.3)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-14-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:
I tried to delete a file from the usb-stick. It doesn't work. Dolphin works but it isn't able to delete file from usb-sticks. It is possible to delete files from the hard drive.

The crash can be reproduced some of the time.

-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
