Bug 271927

Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.35.12-88.fc14.i686.PAE i686
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed:
Right-click, Quit on knote, which was in the system tray.
- Unusual behavior I noticed:
For several days I've found plasma-desktop CPU usage climbing to 100%. Last time I looked at hidden icons, and closed the printer applet, which  fixed it. This time the crash of knote reduced it to backgound levels (top is reporting .01-.02 I type this).

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