Well, to me that sounds like a bug, then, and not one I recall seeing.
So, is there a chance you could gather together the details?:

	- nfs-utils version
	- kernel version
	- steps to reproduce, output from ls -l, whatever

And a network trace covering the time from the mount to the ls -l (or
whatever) showing the incorrectly mapped group might also help.  (Just
run tcpdump -s0 -wtmp.pcap, then mail in tmp.pcap.)
