TypeError: argument of type 'NoneType' is not iterable

[Techno-Fox]

This error appears when trying to fuzz stdin on a program (not arguments, just stdin). However manul forces the @@ which is for arguments.

Error :

Traceback (most recent call last): File "/usr/lib/python3.7/multiprocessing/process.py", line 297, in _bootstrap self.run() File "/usr/lib/python3.7/multiprocessing/process.py", line 99, in run self._target(*self._args, **self._kwargs) File "./manul.py", line 993, in run_fuzzer_instance fuzzer_instance.run() # never return File "./manul.py", line 851, in run self.dry_run() File "./manul.py", line 613, in dry_run if "is for the wrong architecture" in err_output: TypeError: argument of type 'NoneType' is not iterable

P.S. Thank you for taking time to read this issue, and hopefully fix it.
