Bug description:
  gtk-window-decorator crashes each time I close a firefox window in
  which I had a google hangout.

  (Note: There is probably a shorter or more obvious test case, but that's how I reproduce it systematically on several systems)
  1. Open a new tab in Firefox and start a Google hangout
  2. Detach the tab to new window (right-click on the tab, and select "Move to new window" in the contextual menu)
  3. Right-click to title bar of the newly open window and select "Always on top" and "Always on visible workspace" in the contextual menu.
  4. Chat with your friends for a bit
  5. Close the window

  This crash and windows decorations are gone. To recover the decoration, open a terminal and run "gtk-window-decorator &" then close the terminal with CTRL+D (not the close button of the terminal, that'd kill the decoration too)

  The window closes without crash
