Thanks for reporting that.

Get latest cvs. It should work now:

root@linux-dual-head:/mnt# mkdir d
root@linux-dual-head:/mnt# touch d/f
root@linux-dual-head:/mnt# rmdir d
rmdir: failed to remove `d': Directory not empty
root@linux-dual-head:/mnt# rm d/f
root@linux-dual-head:/mnt# rmdir d
root@linux-dual-head:/mnt#
