Application: dolphin (1.5)
KDE Platform Version: 4.5.5 (KDE 4.5.5)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-24-generic x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
I had two dolphin windows opened, one on the local HD and the other pointed to a USB mediaplayer. Shortly after I pointed and moved a lage wav file to the USB mediaplayer the copy process started and about a second after that both windows crashed.

I use KUbuntu 10.10 with KDE 4.5.5 from the PPA repro.

additional point: 
about one minute before crashing dolphin had a strange behavior while marking file for moveing into a backup folder. I did for 5 minutes whithout any problems, but then when ever I marked more than one file (using point and hold with the mouse) and released the left mouse button the file were moved one folder higher whithout a question (question first is my default option).

I HTH and best regards,
M. Menzel

The crash can be reproduced some of the time.
