When I try to launch Synaptic from System -> Administration menu, gksudo (redirected to gksu) asks for the password and after entering the password, it still does not launch Synaptic.

All programs in System -> Administration exhibit the same behavior.

Running 'gksudo synaptic' in terminal produces the same output. Running 'sudo systic' in terminal asks for the user password two times (rejects it the first time, even though the password is correct). After the password is accepted by sudo in terminal, I can use gksudo and sudo from within terminal, but not by using launchers from menus.

The error I get when using 'gksudo nautilus' after the password is accepted by sudo in terminal:
(nautilus:11305): GnomeUI-WARNING **: While connecting to session manager:
