If you can reproduce the crash at will, may you read http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports and post a complete backtrace here?

I think you need to install the "kdegames-debuginfo" package

Thanks :)

I've got a similar bug with the Jigsaw-puzzle type.

I'm using Kubuntu 9.10 with KDE 4.3.5 and Ksudoku 0.5


Here my backtrace:
