Bug 289950

Application: kmail (4.7.4)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.8.0
Operating System: Linux 3.1.1-1.fc16.x86_64 x86_64
Distribution: "Fedora release 16 (Verne)"

-- Information about the crash:
- What I was doing when the application crashed:

Selecting a single message in KMail2.  Message in question had external HTML references, and I have Konqueror configured to use kwebkitpart instead of khtml.

The crash can be reproduced some of the time.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
