Application that crashed: konqueror
Version of the application: 4.3.2 (KDE 4.3.2)
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.3
Operating System: Linux 2.6.31-1-amd64 x86_64
Distribution: Debian GNU/Linux unstable (sid)

What I was doing when the application crashed:
I was just refreshing a tab with Facebook, then Konqueror crashed.

Note : I have the nspluginviewer installed, but blocked, perhaps there is something related...

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