Bug 240807

Application: dolphin (1.4.9)
KDE Platform Version: 4.4.82 (KDE 4.4.82 (KDE 4.5 >= 20100601)) (Compiled from sources)
Qt Version: 4.6.3
Operating System: Linux 2.6.31.12-0.2-default i686
Distribution: "openSUSE 11.2 (i586)"

-- Information about the crash:
- What I was doing when the application crashed:

I mounted the my mobile phone's sd card (a N85). After unmount (using the 'Places' section in dolphin) everything is ok, but when I remove the device from USB, dolphin crashes.

It's always reproductible, seems to happen with all mass storage devices connected to USB (repeated the test with an external HDD and stick).

The crash can be reproduced every time.

-- Backtrace:
Application: Dolphin (kdeinit4), signal: Segmentation fault
