"GetButtonMappingArray" function returns reference to std::vector<...>, right?
Now you should tell Boost.Python how to manage memory of this object.

If this function returns reference to a member variable you can use
"return_internal_reference" call policy (
http://boost.org/libs/python/doc/v2/return_internal_reference.html )
