Wild guess because of lack of context: It's a race condition because you haven't acquired the GIL before calling pyCallEventCallback. You can do so by using PyEval_SaveThread and friends. You have to make sure to call PyEval_InitThreads somewhere, e.g. when embedding from within the interpreter initialisation boilerplate, when extending for instance from within the extension module initialisation. cheers, aa -- Andreas Ames | Programmer | Comergo GmbH | Voice: +49 69 7505 3213 | ames AT avaya . com -- http://mail.python.org/mailman/listinfo/python-list
