Bug 319871

Application: krusader (2.4.0-beta1 "Migration")
KDE Platform Version: 4.10.2
Qt Version: 4.8.4
Operating System: Linux 3.8.0-19-generic i686
Distribution: Ubuntu 13.04

-- Information about the crash:
I was copying over files from one external harddrive to another (a process which I have done before without any crash). The copying had been running for about 60 seconds and seemed to be running smoothly until the sudden shutdown of Krusader.

No other unusual activity was going on (just a standard, unrelated instance of FireFox running in the background).

-- Backtrace:
Application: Krusader (krusader), signal: Segmentation fault
Using host libthread_db library "/lib/i386-linux-gnu/libthread_db.so.1".
