Bug#526807: gnome-panel: shutdown button does not work after upgrade to 2.26

[Norbert Preining]

Package: gnome-panel
Version: 2.26.0-1
Severity: normal

I recently upgraded gnome-panel, gnome-panel-data, and libpanel-applet2-0
to the versions in experimental (2.26.0-1) to fix that extremly annoying bug
that the current unstable version does not allow vertical notification 
areas  (#520918).

Well, one does never get what one wants, now the "shutdown" button is 
greyed out and does not respond to anything.

Is there some magic setup root has to do to make that button work again,
or is it simply not supported in gnome 2.26 to shutdown the computer
from a running session?

Thanks and all the best

Norbert
