Version:           2.1.1 (using 4.1.1 (KDE 4.1.1), Debian packages)
Compiler:          cc
OS:                Linux (x86_64) release 2.6.26.3-toi3-rc7

I used kget from command line to download a file. I cancelled it. No problem so far. Then I went to the Settings dialog and changed some settings. I'm sorry but I can't remember what I exactly changed.

When I closed or applied the settings I got this crash backtrace:

I couldn't reproduce the problem, but maybe I can be given some indications as how to proceed to make sure this is a real problem or not.
