Application that crashed: dolphin
Version of the application: 1.3
KDE Version: 4.3.1 (KDE 4.3.1)
Qt Version: 4.5.2
Operating System: Linux 2.6.30-ARCH x86_64

What I was doing when the application crashed:
I've got two tabs. One from my usbdrive and one from local folder. I copy files from usb to HDD (~15 MB). Nothing strange happens. When I close dolphin, error apears (kde bug report). Thats all.

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