Bug 274932

Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.3 (4.6.3)
Qt Version: 4.7.3
Operating System: Linux 2.6.39-1.slh.1-aptosid-686 i686
Distribution: Debian GNU/Linux unstable (sid)

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

- I have had some programms like kontact and korganizer opened
- I have modified the kde toolbar
- I have killed korgac with ksysguard and other programms (iTalc), because I've recognized massive slowdowns


- Unusual behavior I noticed:

massive slowdowns

-- Backtrace:
Application: Plasma-Desktop-Umgebung (plasma-desktop), signal: Segmentation fault
