Well, you *are* telling nmap to do a ping-scan (-sP) which doesn't use 
ports, but then you specify ports as well.

Quite possibly, some condition has been reversed/reused somewhere where 
it wasn't proper, so that the error message for the opposite condition 
(non-PING scan with no ports specified) is shown instead.

A quick scan of the source-code should tel you if this is the case.
