You need to call CORBA.ORB_init() first. The segfault is caused by it
trying to access code set information that is set up by ORB_init().

It would be nice if it threw an exception rather than giving a segfault,
but I don't really want to add a check for it because that would involve
adding an extra test along the call chain of some really
performance-critical code.

Cheers,

Duncan.
