Taking a screenshot during a game may lead to crash

[Marco Trevisan (Treviño)]

[ Impact ]

A screenshot of the Left 4 Dead 2 or Garry's Mod window causes the gnome-shell to terminate the user's session.

[ Test case ]

- Launch a game (Left 4 Dead 2 or Garry's Mod)
- Open GNOME Screenshot app
- Set "Window" in Capture Area menu and "Delay in Seconds" to 2-3 seconds
- Alt-tab (or switch by Super key) to an open game
- GNOME Screenshot app terminates the user session with an error "something went wrong".

[ Regression potential ]

No screenshot may be taken when requested
