Application: akonadi_imap_resource (4.7)
KDE Platform Version: 4.7.3 (4.7.3)
Qt Version: 4.7.4
Operating System: Linux 3.2.0-rc7 x86_64
Distribution: "Gentoo Base System release 2.0.3"

-- Information about the crash:
- Unusual behavior I noticed:

My internet connection was unstable and I had frequent disconnects. KMail's IMAP resource often crashes during such situations.

The crash can be reproduced some of the time.

-- Backtrace:
Application: IMAP postmaster@kaishome.de of type IMAP E-Mail Server (akonadi_imap_resource), signal: Segmentation fault
