Comment 1 Carl Symons 2011-09-11 17:15:18 UTC 
kubuntu 11.04; kpatience 4.7.0 crashes here too. Don't have any debug information. Gypsy seems to be the culprit. Everything else works fine.
Comment 2 Parker Coates 2011-11-07 04:27:12 UTC 
SVN commit 1262923 by coates:

Remove a bunch of cruft from DealerScene::demo().

This code was doing a bunch of things suboptimally. It didn't use
KCardPile::topCardsDownTo(). It handled a bunch of animation stuff
that should now be handled automatically. It asserted pointers after
having used them, which is pointless.

While I don't know what was causing the crash in bug 274127, I do know
it can't happen again with the new code.
