So there are at least three bugs:

(1)
# rmdir -p /.ssh/agent
rmdir: : No such file or directory

(2)
$ mkdir dir
$ ln -s dir lnk
$ rmdir lnk     # should fail
rmdir: lnk: Not a directory
$ rmdir lnk/    # should remove dir, that's what rmdir(2) does
rmdir: lnk: Not a directory

(3)
# rmdir /	# should return EBUSY, kernel problem
rmdir: /: Is a directory
