sudoku menu items inaccessible

Binary package hint: gnome-games

All menu items, barring the help menu and the three options [Game-> Print Multiple Sudokus], [Game -> Close] and [Settings -> Fullscreen] are grayed out and not responding to clicks. The accessibility of the menus doesn't change no matter if I play an active game, have finished a game or open the new game screen. The toolbar buttons still work though and settings seem editable with gconf-editor (changed /apps/gnome-sudoku/always_show_hints and the game obeyed). The problem is limited to the actual menus in the game as far as I can test as a user.

This problem probably appeared some time during the last two weeks, since that's how long it's been since I last looked at the menus.
