Description of problem:
Even root user is not able to run a sigle test using the sectool-gui in F12/rawhide due to following issue with dbus:

Exception in thread Thread-2:
Traceback (most recent call last):

</snip>

Version-Release number of selected component (if applicable):
# rpm -q sectool-gui
sectool-gui-0.9.4-2.fc11.i586

How reproducible:
always

Steps to Reproduce:
1. run sectool-gui from CLI
2. right-click on any test, firewall for example
3. select "Start the selected test option" 
4. Move to tab "Test Results"
  
Actual results:
The gui says that the test is running, while it will run forever. 
You can observe Exception in Thread-2 listed above.

Expected results:
The test should run cleanly, no exception, ...

Additional info:
This works in F11 using the same packages. Seems to be related to bug #520638.
Also it would be nice to get rid of the "DeprecationWarning"s.
