Bug 325619

Application: akonadi_imap_resource (4.10)
KDE Platform Version: 4.10.5
Qt Version: 4.8.5
Operating System: Linux 3.10.12-100.fc18.x86_64 x86_64
Distribution: "Fedora release 18 (Spherical Cow)"

-- Information about the crash:
- What I was doing when the application crashed:
Was doing nothing special.
Kmail was opened in system tray and backgroud email check was active.
Might also be possible that I had a network connection problems at that moment.

The crash can be reproduced sometimes.

-- Backtrace:
Application: s.karapetyan@betconstruct.com of type IMAP E-Mail Server (akonadi_imap_resource), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
