Description Steven Hollingsworth 2011-12-23 16:01:52 UTC

Version:           unspecified (using KDE 4.7.3) 
OS:                Linux

Usually to make the panel responsive again, I will click add panel to cause a crash which will restart the application and it will work ok for a while.

this happens 2-3 times during an eight hour session.

Applications I frequenty use are rdesktop, konsole, firefox, libreoffice

No other non-standard widgets (that I know of) are loaded.

Reproducible: Always

Steps to Reproduce:
Right mouse click New Activity
-> New Panel
-> Default Panel



Actual Results:  
Crash / restart of application
