Application: konqueror (4.3.72 (KDE 4.3.72 (KDE 4.4 >= 20091015)))
KDE Version: 4.3.72 (KDE 4.3.72 (KDE 4.4 >= 20091015)) (Compiled from sources)
Qt Version: 4.6.0
Operating System: Linux 2.6.31.4-0.0.1.8d115ae-desktop i686

What I was doing when the application crashed:
I restarted KDE after my latest build for this weekend, and Konqueror crashed when invoked.

 -- Backtrace:
