Force Quit icon does not kill anything, nor respond to Esc

[Louis Simard]

Scenario:

I am using the Gnome Classic no-effects session in Ubuntu Precise. I added a panel with a Force Quit applet on it. When I click it, the Force Quit icon brings up a small undecorated window that reads, roughly, "Click a window to force it to quit, or Esc to cancel". I then click the window, and the window's owning program is not killed.

Additionally, pressing Esc does not work, and input to my Gnome session is frozen with the "cross" (+) cursor, without shortcuts available to switch windows or close the undecorated window, until I issue "killall gnome-panel" in one of the text-only virtual terminals.

The expected behaviour is of course that the Force Quit applet works :)
