That what you described :-).

I think that NiString is relevant. Take a look on this FAQ:
http://www.boost.org/libs/python/doc/v2/faq.html#custom_string

Boost.Python has next code:

try{
    run you C++ code
}
catch( registered exceptions ){
     convert them to Python exception
}
catch( ... ){
    throw Python RuntimeError( "unidentifiable C++ exception" )
}

So or you forgot to register your exception or ... something really
bad happened.
