AssertionError: assert path[-2].node is within_node, (path[-2].node, within_node)

[ZdenekM]

I was getting an AssertionError because of this comment. With the comment gone, the error was also gone. Also, everything seems to be ok with the comment on its original place and disabled assertions.

While trying to construct a minimal example, I got a NotImplementedError...
