The NewConnection method is marked as 'ASYNC' in the method table (see 
profile_methods).  In our gdbus library, returning NULL here means that 
the method return is deferred until a later time.  E.g. when we try to 
establish a SLC connection and fail / succeed.

In this patch it is left kind of hanging out there and you would need to 
peek at patch 10 to really know what happens to it.  Confusing, I know ;)
