Version:            (using Devel)
Installed from:    Compiled sources
OS:                Linux

To reproduce:
-Click either "Start new game" or "Restart game"
-While the card are being dealed, click "Demo"
-Kpat crashes.
I dont know if other actions,while dealing cards,crash the application.

Backtrace:
Application: KPatience (kpat), signal SIGABRT
