[Bug 99198] kde-guidance-powermanager-0.8.0 fails with AttributeError: 'NoneType' object has no attribute 'setChecked'

[Benno Schulenberg]

Public bug reported:

Binary package hint: kde-guidance-powermanager

The update to kde-guidance-powermanager-0.8.0 removed the battery icon
from the system tray (after a restart).  Running guidance-power-manager
on the command line produces this:

$ guidance-power-manager

The previous version, kde-guidance-powermanager-0.7.1~svn2007025, worked fine, as far as i could tell.
