Infinite recursion when run without correct permissions #5
Description
On latest git version
commit 25ee90ed9d65c42973be361d22f60b450d22b8dd (HEAD -> master, origin/master, origin/HEAD)
If I try to use the 'is_card_inserted' command without correct permissions it fails doing infinite recursion on getattr.

When running under sudo everything is nice and dandy.

A clearer error would be preferable.
