Bug#312937: gksudo works badly for commands with NOPASSWD

[Martin Schwenke]

Package: gksu
Version: 1.2.5-3
Severity: normal


I add an item to /etc/sudoers so I can run it without a password:

  martins ALL=(ALL) NOPASSWD: /usr/X11R6/bin/xterm

I then run it under gksudo:

  gksudo /usr/X11R6/bin/xterm

I get the following weird behaviour:

  1. The xterm window opens without requiring a password.  Yay!  I
     close the xterm.

  2. The password dialog appears.  :-(

     If I click OK or press the Enter key the password dialog
     disappears and another xterm window opens.

     If I click Cancel I don't get another xterm.

The password dialog should not reappear!

I also see the following error each time an xterm opens:

  Warning: Tried to connect to session manager, Authentication Rejected, reason : None of the authentication protocols specified are supported and host-based authentication failed

I don't get this error if I run sudo instead of gksudo.

Thanks...
