I do not think this is a fault in synaptic or gnome-shell. I can also trigger it by simply doing the following from a command line and then simply wait when prompted for my password:

# pkexec ls
Error executing command as another user: Not authorized

This incident has been reported.

/var/log/auth.log then contains:

So it looks like policykit is the culprit.
