As shown in the Debian bug report , the dash-dash style properties produce errors within KDE, as QtDBus does not treat "-" as valid character for properties.
See also the discussion at .
As a consequence, the properties in e.g. DeviceKit-disks and DeviceKit-power have been changed to FirstLetterCaps style .
Please consider to do the same for ConsoleKit so it is usable within KDE.
