Bug 194943

Application that crashed: kpat
Version of the application: 3.1
KDE Version: 4.2.88 (KDE 4.2.88 (KDE 4.3 >= 20090527))
Qt Version: 4.5.1
Operating System: Linux 2.6.29-gentoo-r5 i686

What I was doing when the application crashed:
I've been getting crashes recently in KPat, and it always seems to be about when the solver is about to decide whether the game is still winnable.

 -- Backtrace:
Application: KPatience (kpat), signal: Aborted
