That's a known bug which was fixed in 2.1.17
<https://bugs.launchpad.net/mailman/+bug/1251495>.

That's the wrong fix. The correct fix is to change the spelling from
Delete=False to delete=False

That was unnecessary. When Python imports a module, and there is a .py
and a .pyc and maybe a .pyo, it checks the time stamps and if the .py is
more recent, it loads that and compiles it and if it has permission,
(re)writes the .pyc.

As I note above, fixed in 2.1.17, and the final 2.1.18 release will be
this weekend barring any unforeseen personal emergencies.
