Comment 17 for bug 9214

mvo,

gksudo still gives a message to stderr if the wrong password is entered, but it exits with status 0. If gksudo is invoked by a program not run from a terminal (as it commonly is) then there is no visible indication of what has gone wrong.

For example feisty's update-manager runs gksudo to install the updates, but if I type the wrong password I'm just returned to the update list with no indication what happened.
