I tested and it is not your fault.
It's about the python bindings that seem not to support certain C++
constructs (in particular private virtual methods).

I have just pushed a fix to master, so if you are working with that your
code should run fine now (or with the next nightly).

This can also be backported to 2.8.2.

I would appreciate a short feedback if it also workd for you.
