Review: Needs Fixing testplay, crash

Opps, I got some nasty crash here (Playing Frisians on checkmate)

This smells like trying to set a tooltip for some already freed button?

Not sure If I can reproduce this. I will need a debuuger that will keep my Gamewindow
open just at the time of the crash.

Gun: Do you have an idea? or where could I attach more infos (complete crashdump, savegame etc.)

Will try to give it another tray with a debugger
