Bug 303406

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:
- What I was doing when the application crashed:

Before the crash I was viewing messages in a different IMAP Inbox.
Clicking on the Inbox icon for Gmail causes an instant crash.
This happens roughly once a day when being used all working day.

The crash can be reproduced some of the time.

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