Application: plasma-desktop (4.11.2)
KDE Platform Version: 4.11.2
Qt Version: 4.8.2
Operating System: Linux 3.2.0-56-generic-pae i686
Distribution: Ubuntu 12.04.3 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I was playing with the grouping options, had 4 everpad note windows and sflphone all grouped.  I exited sflphone so I could check to see whether grouping was working.  I didn't get a chance to restart sflphone.  I was attempting to force grouping using a group ID.  I used "Special Application Settings" to group sflphone, and "Special Window Settings" for everpad all 5 windows in the same tab group; because I wasn't sure which of the two types of settings (Window or Application) to use, so I was experimenting. (By the way...shouldn't all of the tabs get the same ID propogated when I fill one ID in, if they're already grouped?)

- Unusual behavior I noticed:
In place of my sflphone tray icon after exiting sflphone, there appeared what looked like half an icon.  Clicking on it resulted in the entire bottom panel disappearing, and an icon appearing on the desktop.  Attempted to get the panel back by clicking on that icon,  it jumped to a different position on the screen, I left clicked, right clicked several times in no particular order until finally the it all just crashed.

I have 6 virtual desktops.  I have 3 instances of chrome running (each with about 6 tabs), 3 Konsole windows, 4 LibreOffice -Writer windows  and skype too.  I have KNotes & Kontact running in a different desktop (shouldn't I only see things in the tray that are displayed on the current desktop?)
