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. -- Backtrace: Application: Plasma-Desktop-Umgebung (plasma-desktop), signal: Segmentation fault [Current thread is 1 (Thread 0x7f6599851780 (LWP 2415))] Thread 8 (Thread 0x7f657c921700 (LWP 2419)): #0 0xffffffffff60017b in ??
