NAT breaks lots of things from the Internet Protocol layer up.  In general,
it's not reasonable to expect a protocol to run over NAT  unless someone
has analyzed the protocol and the implementations of the protocol and
determined that they don't violate any of a fairly large number of
(quite reasonable) assumptions.  
(see for a list)

This is an inherent characteristic of any NAT implementation.  The only
'bug' is that the problems with NATs are not adequately documented - so 
people blame the app or the protocol for problems caused by the imposition
of NATs.
