Bug 262756

Application: plasma-desktop (0.4)
KDE Platform Version: 4.5.95 (4.6 RC2)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-24-generic x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:
During the last days I had the same issue several times: Started Kontact and KTimetracker externally. After a while, the plasma workspace runs into heavy load. Sometimes it crashes, and one of these crashes I am reporting hereby. Appears under 4.6 RC1 or 2.

- Unusual behavior I noticed:
As the 4.6 KTimetracker integrated in Kontact does not offer any usable funtionality anymore (e.g. load a task list), I need to start this application externally in order to work with it. But essentially, KTimetracker is not usable anymore.

The crash can be reproduced some of the time.
