Comment 1 Dario Andres 2010-03-25 11:57:48 UTC

The crash is caused by the STasks widget.
Please, recompile/update it.
Regards

Comment 2 DarkMac 2010-03-25 14:03:54 UTC

It has nothing to do with stask widget because i dont have stask widget on my panel. I`m using the classical task manager. I`ve also tried several time to add yawp to panel and even to system tray.
When i add yawp on the system tray through system tray settings - plasma widget - check yawp then click on.. nothing happens. If i go back to system tray settings - plasma widget the yawp is not checked.
When i try to add yawp directly to panel sometimes it is adding a error icon and when i move the mouse over it it says: Unable to add widget. Could not find requested component yaWP.
Offcourse yawp is installed (ver. 0.3.2-3.1)
Things that i`ve already tried: 
- removed plasma* from .kde/share/config.
- removed .kde folder entirely.

Comment 3 Dario Andres 2010-03-25 22:07:05 UTC

1) The crash is related to the STasks widget (according to the backtrace..):

Thread 1 (Thread 0xb5346980 (LWP 16026)):

#6  0xa6a492c7 in TaskManager::Task::window() const () from

"/usr/lib/kde4/plasma_applet_stasks.so"

2) If you get a message like "Unable to add widget. Could not find
requested component yaWP." there is probably an installation issue. Try reinstalling the yawp package and run "kbuildsycoca4 --noincremental" on Konsole. Then restart your KDE session and try again.
