Hi,
I'm filing a separate bug report for this issue.
When I record a demo and complete one of the tutorial levels, the game will crash.
This is related to the use of -D_FORTIFY_SOURCE=2 in Debian that exposes this bug.
The error message is:
berusky2: kofola/Demo.cpp:48: int demo_Check_Owner(WCHAR_, char_, WCHAR*):
Assertion `0' failed.
