Application: dolphin (1.4)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-22-generic x86_64
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
I open two Dolphin windows, one to ~/Storage/Videos and one to /media/FLIPVIDEO/DCIM/ and copy *.avi files from the FLIP to the HDD.  Sometimes I copy, sometimes I move.  About 1 in 5 attempts causes a dolphin crash.  The annoying thing is, I can't find a pattern.  Sometimes the exact same process works, sometimes it crashes.  I can definitely reproduce if needed.  I'm running Kubuntu 10.04, fresh install with all updates as of May 10, 2010.

The crash can be reproduced some of the time.

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