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 2.6.38-8-generic i686
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:
I had two tabs open, both showing me the contents of the same remote server via sftp. The view mode was "Columns". I clicked on a item. Sorry I can't remember whether it was a right or left click on a directory, a file or the context menu. But it wasn't the menu bar or the icon bar. This happened the first time and I was doing nothing I usually won't do. So if it happens again, I will let you know.

- Custom settings of the application:
KDiff3 is installed as a right-click extension. The crash happened a few minutes after the KDiff3 comparison described below. My OS is Ubuntu 11.4 with a later installed and used KDE desktop.

- Unusual behavior:
I did some KDiff3 directory compares before and during the comparison, a windows complained that the file "/tmp/??" already exists. I was comparing two directories via sftp on the same server. I guess the /tmp/ file was a local copy of the currently compared remote file. I don't know whether or not this is related to this bug.

The crash does not seem to be reproducible.
