quadrapassel crashes with 'BadDrawable (invalid Pixmap or Window parameter)'

Binary package hint: gnome-games

TEST CASE:
1. Launch quadrapassel
2. Select menu: Settings / Preferences
3. Select Tab 'Themes'
3. Select Tab 'Games'
5. Click on 'Close'

Result:
The application crashes with the following error:
$ quadrapassel

(quadrapassel:13429): Clutter-CRITICAL **: Unable to make the stage window 0x8400005 the current GLX drawable

(quadrapassel:13429): Clutter-CRITICAL **: Unable to make the stage window 0x8400006 the current GLX drawable

(quadrapassel:13429): Clutter-CRITICAL **: Unable to make the stage window 0x8400007 the current GLX drawable
The program 'quadrapassel' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadDrawable (invalid Pixmap or Window parameter)'.
  (Details: serial 149 error_code 9 request_code 137 minor_code 7)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)

This is reproducible in both Classic Desktop (no effect) and Unity
