Application that crashed: konqueror
Version of the application: 4.3.5 (KDE 4.3.5)
KDE Version: 4.3.5 (KDE 4.3.5)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-20-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
I was logged into facebook only for a few minutes and then logged out, causing Konqueror to crash. No other tabs were open at the time. This is 100% reproduceable.

 -- Backtrace:
Application: Konqueror (kdeinit4), signal: Aborted
