crash on GTK quartz

[Jonatan Liljedahl <lijon kymatica com>]

I've built GTK on macports with +quartz +no_x11 +universal,

my application builds fine but then crashes after a while with:

2008-11-01 16:58:03.272 algoscore[4632] unlockFocus called too many time.

I'm using a GtkDrawingArea, drawing on it with Cairo.
