Darned if I know. However, there are two comments.

1. The standard way to check for None is to use the
"is" operator, not the "==" operator. You might try
that. The equals test ought to work, though.

2. However, the even easier way to do it is not to do
a check at all, but simply rely on the fact that both None
and the null string act like False in an if statement. In
other words, just remove the "== None" and see what
happens.
