In what ways would Python be considered a more stable language than Ruby?

I have been using Ruby for a while and I find that because if its metaprogramming capabilities it makes things harder to debug and 3rd party code can potentially cause bugs in what you would think would be unrelated areas of your application.

Is python's metaprogramming much tamer and as a result it is easier to keep things under control? I'm not sure if stable is the right word for it but just less-magical in nature which results in more maintainable and understadable code.

If someone knows both python and ruby maybe they can explain if this is true?
