Bug#432153: /usr/share/gdm/gdmXnestWrapper not executable, so nested login doesn't work

[Ming Hua]

Package: gdm
Version: 2.18.3-1
Severity: normal

After upgrading to gdm 2.18.3-1, which reworked login with a nested X
server configurations, nested logins stopped working.

The menu item for nested login disappeared from my GNOME menu, and
running "gdmflexiserver --xnest" command from
/usr/share/applications/gdmflexiserver-xnest.desktop gives a error
dialog window with:

    Cannot start new display

    The nested X server (Xnest) is not available, or GDM is badly
    configured.
    Please install the Xnest package in order to use the nested login.

Looking into the .desktop file, I found the line
"TryExec=/usr/share/gdm/gdmXnestWrapper".  And this file is not
executable.  I changed it to executable, and now command "gdmflexiserver
--xnest" works.  I haven't logout and re-login to check the menu item
yet, but I expect that to work as well.
