Application: dolphin (1.4)
KDE Platform Version: 4.4.00 (KDE 4.4.0)
Qt Version: 4.6.1
Operating System: Linux 2.6.31-20-generic i686
Distribution: Ubuntu 9.10

-- Information about the crash:
Dolphin crashed after pressing the stop button in the notifications systray.

1. Before this I deleted a log file in a folder in Dophin it was a log file.
2. I could see the logfile disappear (has been moved to trash)
3. A moment later the server created the logfile again - the file re-appeared
4. I hit Ctrl+Z to undo the deletion 
5. A message appeared that that file already exists.
6. I think that I deleted the file again - The notification systray showed a process in action.
7. After hours I realised that there is a process running in the systray
8. the crash log appeared after hitting the stop button in the notification systray
