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
