Interesting, I've got other errors.

Using Visual Studio 2003, I got warning during compilation and
TypeError during runtime, which says, that Boost.Python is not able to
construct rvalue, std::auto_ptr< your class >, from the Python object.

Using gcc 4.2.3, on Ubuntu the generated code didn't compiled and when
I fixed it, than everything was fine and worked as expected
I attached source code, "fixed" generated code and small tester.

What is your environment?

Any way, it seems that I found solution. The only change was to
extract std::auto_ptr<> as is, by value, from Python object.

Let me know, if this really solves your problem, I will fix Py++.
