svnadmin partial results are valid but processing is incomplete

I'm running SVN under Windows Server 2k3 using Apache 2.2 and running
subversion 1.4.5.

$ svnadmin --version
svnadmin, version 1.4.5 (r25188)
   compiled Aug 22 2007, 20:56:15

The following repository back-end (FS) modules are available:

* fs_base : Module for working with a Berkeley DB repository.
* fs_fs : Module for working with a plain file (FSFS) repository.

When two users of the system run 'svnadmin create --fs-type=bdb
G:\svn_repos\foo' it works fine. When another user (who happens to be a
domain admin) runs the same command we get:
svnadmin: Can't stat directory 'G:\svn_repos\foo\db': Partial results are
valid but processing is incomplete

The repository directory 'foo' is not created.

We've double-checked the permissions. This user can create directorys
under G:\svn_repos. He is, in fact, a domain admin and should have *more*
permissions than I do.

Any thoughts?
