Bug 296157

Application: kmail (4.8.0)
KDE Platform Version: 4.8.1 (4.8.1) "release 481"
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:
started kmail --> click on mail in Inbox --> crash
Does not always happen, but it crashes very often (sometimes when I open the third or fourth email)
Producable after every restart of kmail, KDE and the whole computer as well.

Happens the same when I use kmail within the Kontact shell.

The crash can be reproduced some of the time.

-- Backtrace:
Application: KMail (kmail), signal: Aborted
