Bug#389254: gksu: xxxx

[Matthijs Melchior]

Package: gksu
Version: 1.3.6-1
Severity: important


Subject: "gksu xterm" fails when using ssh X forwarding
Package: gksu
Version: 1.9.4-1
Severity: important

There is a difference in behavoiur of 'gksu xterm' depending on the
type of X display connection.  'gksudo xterm' works fine.

When logged in on the local display, with DISPLAY=:0.0, both 'gksu'
and 'gksudo' work as advertized.

However, when using the Cygwin X-server to display a Gnome desktop
on my Windows machine and connect through ssh to an X session on a
Debian Linux machine, giving DISPLAY=localhost:10.0, then gksu fails 
with the following message:
"X connection to localhost:10.0 broken (explicit kill or server 
shutdown)."
The apparant reason for this is available on the ssh stderr:
"X11 connection rejected because of wrong authentication."

The simplest way to demonstrate this on a local console desktop is
to use 'ssh -f -Y localhost xterm" and use both gksu and gksudo in
that xterm.

Please make 'gksu' work independent of the type of X connection.
