[Bug 55240] Aisleriot occasionally crashes when dragging cards

[Paul Nolan]

Public bug reported:

Binary package hint: gnome-games

In edgy (gnome-games_1:2.15.5-0ubuntu1) Aisleriot sometimes crashes when
dragging cards between piles. I think it happens when I overshoot with
the mouse, but I'm not sure.

Here's the backtrace:
