Comment 1 Frank Reininghaus 2012-10-29 19:41:40 UTC 
Thanks for the bug report! Looks like a KIO issue. Is the crash reproducible for you? If yes, it might be helpful if you could run Dolphin in Valgrind using

valgrind dolphin 2>valgrind.log

and attach the log file here.
Comment 2 martinstingl 2012-10-29 20:56:29 UTC 
I tried several times but was not able to reproduce the behaviour.

Comment 4 rihokalbus 2012-11-08 08:33:55 UTC 
I copied same file multiple times and it happended randomly (twice), source tab was in my home directory, destination tab was samba share on Windows7 machine. 
Will try with valgrind.

Couldn't reproduce this crash anymore. Neither with or without valgrind.
Comment 6 Frank Reininghaus 2012-12-03 09:23:21 UTC 
Thanks for the feedback. If you see this crash again in KDE 4.9.3 or later, please reopen this report and provide any new information that you have (like, e.g., steps to reproduce the crash or a Valgrind log). Thanks for your help!

dolphin (2.0) on KDE Platform 4.8.5 (4.8.5) using Qt 4.8.1

- What I was doing when the application crashed:
Two tabs open dragging files from one to another.
