I post this question (and answer), so if anyone else has this problem in the future, you can post it.
If you are trying to run celeryd in Django like this:
python manage.py celeryd
You may receive the following error immediately after it starts:
celery@eric-desktop-dev has started.
Traceback (most recent call last):
File "manage.py", line 11, in <module>
execute_manager(settings)
<... snip ...>

self.write_long(len(s))
TypeError: object of type 'NoneType' has no len()
A rather cryptic error message that does not have real information about where to go to fix the problem. Below is the answer, so you do not spend a lot of time on this error, as today :)
