Bug 313804

Application: akonadi_imap_resource (4.9)
KDE Platform Version: 4.9.5 "release 3"
Qt Version: 4.8.4
Operating System: Linux 3.4.11-2.16-desktop x86_64
Distribution: "openSUSE 12.2 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed: From the last few days, this kind of crash happen from time to time. 
Those resources are there from a long time, and were working.
This crash for example happen during the night when the computer was idle.

All those kind of trouble happen now, cause the nepomuk database was cleaned adn restarted from scratch

The crash can be reproduced some of the time.

-- Backtrace:
Application: 01_bruno of type IMAP E-Mail Server (akonadi_imap_resource), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
