Application: dolphin (1.4)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.31-21-generic i686
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
After intense "house keeping" of a large, personal data pool (copying, pasting, moving, renaming or correcting a lot of files, links and folders), Dolphin 1.4 became very, very slow and nearly inoperable, till i have closed it. After closing, this dialog came up. "top" command or the (dual)cpu-monitor-widget did not show any "appropriate" cpu-load and also the network trafic was low (it did not yet happen often).

The crash can be reproduced some of the time.

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