Application: kmail (1.13.6)
KDE Platform Version: 4.7.00 (4.7.0)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-11-generic i686
Distribution: Ubuntu 11.04

-- Information about the crash:
KDE was loading (applications like kopete and firefox was loading in background), Kmail was downloading and generating preview of new email and I was trying to open atached file but all I managed to do was hover mouse over atached file. I was trying to click on it but system was to busy to respond.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
