Solved.
Error description:

struct Color{
    static const Color red;
    ...
    void do_smth( const Color& other = red );
    //The error was raised from the line that register this function,
    //because boost.python tries to create an python object from "red"
    //but Color class is not registered.

}

Solution

mb = module_builder_t( ... )
mb.class_( 'Color' ).always_expose_using_scope = True

This will fix the problem. In future py++ will find this situation and
will generate
proper code.
