Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.00 (4.6.0) "release 6"
Qt Version: 4.7.1
Operating System: Linux 2.6.37.1-1.2-default x86_64
Distribution: "openSUSE 11.4 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
Trying to get the activity with the active widgets back to screen 2 after the new activity manager moved them to screen1
- Unusual behavior I noticed:
Unable to configure screen 2 -- any configuration is applied to screen 1.  Additionallly, trying to move an widget from screen1 to screen2 results in the widget disappearing.
- Custom settings of the application:

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