Trouble importing from public CVS repo

I'm trying to convert this public repo into a git repository:

    :pserver:anonymous@cvs.lysator.liu.se:/cvsroot/unfs3

cvsps seems to produce a nice long list of patchesets for the "unfs3" module, and running

   cvs -d:pserver:anonymous@cvs.lysator.liu.se:/cvsroot/unfs3 co -P unfs3

works as expected.  However, running

   [jgarzik@core unfs3]$ git-cvsimport -v 
-d:pserver:anonymous@cvs.lysator.liu.se:/cvsroot/unfs3 unfs3

produces

Initialized empty Git repository in /spare/repo/unfs3/.git/

This machines and package (git-cvs-1.5.3.3-3.fc7) work just fine with a large number of other CVS repositories [nice work].
