[Jython-bugs] [issue2441] 'NoneType' is not iterable in _nt_quote_args in spawn.py when setup() is called

[Tom A. <re...@bu...>]

New submission from Tom Alexander:

'NoneType' is not iterable in _nt_quote_args in spawn.py when setup() is called. This was tested using Jython 2.7.1b2. 

Here is a stacktrace:

08:42:12 TypeError: 'NoneType' object is not iterable

And here is a patch: https://github.com/jythontools/jython/pull/26

Explanation: This arguments list eventually gets joined via a ' '.join([arguments]) and there is a None in that list. Obviously you can't join None to a string. I'm not sure *how* the arguments list has a None value, but I ran into this.
