Bug 294125

Application: kontact (4.8.0)
KDE Platform Version: 4.8.00 (4.8.0 "release 2"
Qt Version: 4.8.0
Operating System: Linux 3.1.9-1.4-desktop x86_64
Distribution: "openSUSE 12.1 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
Just sending a (signed) eMail. Nothing special at all. Since KDE 4.8 upgrade, the regular crashes of Kontact/KMail are back. The situation has been a lot better already in 4.6/4.7

The crash can be reproduced some of the time.

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