Bug 327864

Application: akonadi_imap_resource (4.11)
KDE Platform Version: 4.11.3
Qt Version: 4.8.6
Operating System: Linux 3.12-0.slh.3-aptosid-amd64 x86_64
Distribution: Debian GNU/Linux 7.2 (wheezy)

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

Putting information into an word dokument in an virtual machine executing windows 7.
It was like always, from time to time the akonadi connector crashes, no obvious reason, maybe an backgroung action......

-- Backtrace:
Application: Schintech vom Typ IMAP-E-Mail-Server (akonadi_imap_resource), signal: Segmentation fault
