gksudo doesn't report failure nicely when user is not in sudoers

[Erik Bågfors]

gksudo doesn't report that user can't "su".

This means that a none-sudo-capable users can go to the computer menu, select
for example "system configuration" -> "synaptic", get a question about password
and then NOTHING.

To make it worse, when this has happened once, gksudo doesn't ask for the
password again, now going "system configuration" -> "synaptic" doesn't even ask
for a password or anything.

If I run "gksudo" from a command line I get "user is not in the sudoers file.
This incident will be reported", which of course is not a good error message for
use in X but would still be better than none.

This needs to be fixed for a multiuser environment.

Regards,
Erik
