Just got the same backtrace (with trunk version of KPat). What I did: 1. Started "Aces Up" game 2. Moved few cards away (according to game's rules) 3. Went to Settings menu and clicked "Enable Solver" => CRASH
Hmm. I'm guessing this is a race condition between the threads. That might explain why I'm unable to reproduce it here.
