Bug 303050

Application: kmail (4.8.4)
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-26-generic x86_64
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
For e-mails with html and images from the internet it comes to crashes when move / delete, etc. Only maybe if I turned off its html and load references can delete the message. Use Update to 4.8.4 with Kubuntu 12:04

The crash can be reproduced some of the time.

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