Application that crashed: kontact
Version of the application: 4.3.2
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-14-generic x86_64

What I was doing when the application crashed:
When I close Kontact and try to restart the application it crashes.  It won't even register a crash when trying to load kontact directly, but when I try to start Akkregator it displays the crash report.

kontact PID: 1662 Signal: 11 (Segmentation fault)

 -- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
The current source language is "auto; currently c".
