I exposed two classes to python:

BOOST_PYTHON_MODULE(client)
{
class_<Error>("Error")
   .def("GetErrorCode", &Error::GetErrorCode)
   .def("GetDescription", &Error::GetDescription)
   .def("__nonzero__", &Error::operator bool);

class_<Client>("Client")
   .def("Execute", &Client::Execute);
}

Here is declaration of Execute method:

void Client::Execute(boost::python::object callable)
{
    Error e;
    callable(e);
}

Here is my python code:

import client

def on_execute(error):
    print error.GetDescription()

c = client.Client()
c.Execute(on_execute)

This fails with Segmentation fault. Debugger says me that can't convert Error object to python. How to resolve this problem?

Can you add the stack trace to your question? – rectummelancolique Jul 03 '13 at 12:10
Also, in your python code, don't you mean `c.Execute(...)` rather than `e.Execute(...)`? – rectummelancolique Jul 03 '13 at 12:12
Yes it is c.Execute(...). – sgeorgiev Jul 03 '13 at 12:33
Ok. Without a C++ side stack trace, you won't get much help, though. – rectummelancolique Jul 03 '13 at 12:48
Any chance for a [sscce](http://sscce.org/)? I cannot reproduce the error. Instead, it executes without failure. – Tanner Sansbury Jul 09 '13 at 16:53
