I'm working on it.. There were 3 main problems with the NFSv3 code left;
one was NULs showing up in files (this has been fixed), the other two
are directory read problems and this one. Unfortunately, I had less time
than expected to work on this, and have been thinking about a clean fix
for the 2nd problem for a bit too long. Still, I should get around to
looking at this particular problem RSN (really!).

Mind you, I certainly wouldn't mind if someone else had a look and filed
a send-pr :-)
