Application: dolphin (1.4)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.33-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
Hi devs, well, I was moving some pictures from a SD card to my desktop. After moving them all I made an accidentally Undo so all pictures from my desktop start moving again but back to card this time. When the notification applet opened showing the progress bar I clicked the stop button and there was when Dolphin crashed.

Note 1: pictures stop moving back and Notification Applet (sorry if it's not its name) shows this with a succeful message.
Note 2: sorry for my bad, really bad english.
Note 3: Arch Linux + KDE SC 4.4.2 is the way to go!!!

Thank you very much for all your kind work, best =)
Martin
