Fun with NULL pointers, part 1

Poliykit plays a role: If you go look at the discussions on the fedora list you'll see that there was some degree of argument what the actual behaviour was— Was it asking for a password at all (some people thought it wasn't because it only did so once) and was it asking for the root password? A lot of people had used and never realized that it was asking for their user password rather than root.

SUID is more unambiguous.
