It wants the name of a class or a function and will auto-complete but if
imenu is not finding and to start with there will be nothing you enter
here!

Some people say "Ping?".

The pattern in python-nav-beginning-of-defun-regexp does not seem to be
the culprit.  It matches both of these.

Yes, that's what python-nav-beginning-of-defun-regexp does.  Nothing
after the name is examined.  In fact, it matches a def with no '(' at all.

The problem appears to be somewhere else, most likely in
python-imenu--build-tree as you say.
