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

I'm using Nvidia proprietary drivers 319

With default drivers probably problem wasn't exists or at least happens much less frequent.

All I was doing was switching terminals to run top to figure out why I had an apport process eating up a whole core. I'm not sure at what point during the crash I was observing, but it seems to have sent me to this bug.

Unfortunately I can hardly reproduce this, but all this should be caused by the missing finalization of the internal menu.
