Bug 228513

Application: dolphin (1.4)
KDE Platform Version: 4.4.00 (KDE 4.4.0)
Qt Version: 4.6.2
Operating System: Linux 2.6.31.12-174.2.22.fc12.i686.PAE i686
Distribution: "Fedora release 12 (Constantine)"

-- Information about the crash:
I was copying or moving files from an USB pendrive to a drive that is in an usb hard disk. Sometimes, when I cut some files from the pendrive to move it to the hd, when i press to the hd dolphin tab, the app crashes.
It's simlar to other bugs, but I think is quite different so I post is as a different one. 

Fedora 12 KDE 4.4 from apt-kde repo.

The crash can be reproduced some of the time.

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