Comment # 1 on bug 965071 from Egbert Eich

Does this also happen when you don't use the docking station?
It could be the screen saver that activated and got confused buy a 'time warp'
happening at resume. In fact, it could be so many things. I'd have to see the
system exactly in the state where this is happening.
This problem likely requires a thorough investigation - it's unlikely to get it
fixed without just by staring at a log file.
