In German iClone 7.41.2525.1 seems to be a problem with Motionlive and LIVEFACE and Leapmotion when trying to add these gears to a character.
After clicking on the plugin name after "Add Gear" nothing happens and the Console Log prints AttributeError Message. Tested this on four different machines with same result.
