Bug 316579

Application: kmail (4.10.1)
KDE Platform Version: 4.10.1
Qt Version: 4.8.3
Operating System: Linux 3.5.0-25-generic i686
Distribution: Ubuntu 12.10

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

I was trying to read some IMAP mails. The mails was unable to load (in a a reasonable time) in imap folders (a very usual problem). I need restart Kmail to load the emails often.

The crash can be reproduced sometimes.

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