Application: kontact (4.9.4)
KDE Platform Version: 4.9.4
Qt Version: 4.8.2
Operating System: Linux 3.5.0-20-generic x86_64
Distribution: Ubuntu 12.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:
Just started Kontact, wanted to check mail - but the mail content never showed up. Instead I stared at an empty window for a while, until it crashed.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
