Application: dolphin (1.4)
KDE Platform Version: 4.4.3 (KDE 4.4.3)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-22-generic i686
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
I was downloading files (from an external application) into my downloads folder. Simultaniously I was viewing different files from that folder and cleaning it up using dolphin. I had some files selected and was trying to select more when dolphin crashed. I glanced at the backtrace and it seems to possibly be because somewhere in the preview code?

The crash can be reproduced some of the time.

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