When running some test cases via py.test and using a coroutine created inside of cythonized code, I get the following: def _format_coroutine(coro): assert iscoroutine(coro) coro_name = getattr(coro, '__qualname__', coro.__name__) filename = coro.gi_code.co_filename if (isinstance(coro, CoroWrapper) and not inspect.isgeneratorfunction(coro.func)): > filename, lineno = events._get_function_source(coro.func) E TypeError: 'NoneType' object is not iterable This appears to be because this line: https://github.com/python/asyncio/blob/2a19f9329f4ee710fef7728b316aa4fe1d07dbef/asyncio/coroutines.py#L289 Is expecting to get back two values, but because of: https://github.com/python/asyncio/blob/master/asyncio/events.py#L35 This it only gets back None. > /usr/local/lib/python3.4/asyncio/events.py(25)_get_function_source() -> if _PY34: (Pdb) func <cyfunction ProgressTracker._do_report at 0x7fdd2fc46498>

Thanks! I've fixed this in the git repo now (https://github.com/python/asyncio/commit/0c3e6ec0340f45d5f6989391358d44b8e974858e). It will be merged into the CPython repo at the next opportunity (before 3.5.2).
