Description of problem:
Started gnome-2048 in a VirtualBox guest of F22. Crashed on startup. Messages on startup are:

(gnome-2048:2519): GLib-GObject-WARNING **: The property GtkAlignment:left-padding is deprecated and shouldn't be used anymore. It will be removed in a future version.

** (gnome-2048:2519): WARNING **: game.vala:121: Failed to save game: Failed to open file '/home/tobias/.local/share/gnome-2048/saved': Datei oder Verzeichnis nicht gefunden

(gnome-2048:2519): Gdk-ERROR **: The program 'gnome-2048' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadMatch (invalid parameter attributes)'.
  (Details: serial 446 error_code 8 request_code 72 (core protocol) minor_code 0)
  (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 GDK_SYNCHRONIZE environment
   variable to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)
