-- Information about the crash:
- What I was doing when the application crashed:

This crash occurred when starting a new game after playing for a while. I don't know if it is related but I often get random display corruption where cards don't render properly.

The crash can be reproduced sometimes.

-- Backtrace:
Application: KPatience (kpat), signal: Segmentation fault
