I also can easily reproduce this one by quickly right-clicking in OpenGL mode a 
second time before the context menu of the previous click has opened.
The stack trace I get:

Application Specific Information:
*** Terminating app due to uncaught exception 
'NSInternalInconsistencyException', reason: 'Menu to be set as submenu is 
already a submenu of some menu.'
abort() called
terminating with uncaught exception of type NSException

The exception text and the stack trace looks like some race condition when 
creating the context menu?
Maybe some synchronization of these COROUTINE stuff needed when processing a 
previous right-click is not yet finished?

This is with 5648.
