Remove directory failed even as root

I am trying to remove a directory and it fails:

[root@pmds-n48 autoit]# rm -rf /home/pick/.gvfs
rm: cannot remove '/home/pick/.gvfs': Is a directory

When I checked the permission, it has all ?

d??????????  ? ?    ?             ?            ? .gvfs

selinux has been disabled and there are no errors in the logs.

That “directory” is not on disk. It represents GNOME virtual file system. See GVfs - Wikipedia
