Application: konqueror (4.6.2 (4.6.2))
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-11-generic x86_64
Distribution: Ubuntu 11.04

-- Information about the crash:
I used krename to rename some files, but some renames were not possible because my files had duplicate names.

The rename job did not complete, but instead remained in progress under the information icon.

I ignored it and finished my work, copied the files to a network share, and prepared to close konqueror. At this time, I pressed the "stop" button on the hung job in the plasma widget.

Konqueror then crashed.

-- Backtrace:
