cvsimport error when modulename is '.'

in an empty directory I'm attempting the command:

git  cvsimport -A ../authcvs-conv -k -m -v -d:pserver:anonymous@opendkim.cvs.sourceforge.net:/cvsroot/opendkim .

this results in ...

Fetching vsignore   v 1.1
Unknown: error

The resulting directory is empty apart from a empty initialised git repository.

git version 1.7.0.rc2.13.g8b233.dirty cvsps version 2.1

numerous permutations of attempting this import have failed. Also fails with
 the CVS module aliases 'world -> .' and attempting to use "world" as an alias name.

I'm happy to assist in debugging this if required.
