stopping mediamanager?

I ran into this problem when dealing with media devices.  I'd look at  
MediaBrowser and DeviceManager code (and other related code, like  
possibly MediumPluginManager) for what was done to fix it.   
Essentially, it iterates through the list of mediums returned by the  
DCOP call and called mediumAdded normally.  You have to be careful  
though because there needs to be a delay for people not running KDE as  
their desktop (4 seconds or so should be enough) to get kdeinit and  
dcop up and running.  You may want to put code to fix it in the same  
place as the code that helps DeviceManager.
