Mahjongg will segfault on Gnome2. Also the Tiles do not display. I think the problem is that mahjongg does not find its pixmaps. I'm not sure if this is a Gnome2 issue or an ebuild issue. NOTE: You can make it segfault by opening the setings dialog.
fixed in later revisions: energe -u gnome-games
I did emerge -u gnome-games Started mahjongg and still had the same problem.
please make sure your installed version is gnome-extra/gnome-games-2.0.1-r1
Went and did a qpkg gnome-games which showed that both gnome-games-2.0.1 and gnome-games-2.0.1-r1 installed. Unmerged both and emerged 2.0.1-r1 every thing works now. Thanks.
