Version: 4.1.85 (4.2 beta 2) (using Devel) OS: Linux Installed from: Compiled sources Looks similar to this 174569 but I had it in a newer version (KDE 4.2 beta 2). I was setting panel options when it crashed, attached backtrace was generated, wallpaper and other settings (already saved before) were re-set to default.
Created attachment 30096 [details] kcrash.backtrace
What QT version do you have? This seems to be a duplicate of bug 176510 (a QT bug already fixed in qt-copy and Qt 4.4.4 / 4.5 ) Thanks :)

It seems like that QT version from Ubuntu doesn't include the patch which fixes this bug. Marking as duplicate of bug 176510 *** This bug has been marked as a duplicate of bug 176510 ***
