bug#27712: 26.0.50; ffap in python-mode

[kootenpv]

In python-mode, with elpy loaded (seems to have no effect), nothing has
effect. I'm just doing "ido-find-file". The trace shows ffap in there.

This is the debugger info:

Does "have no effect" mean you can reproduce this without loading elpy?
Or is the only effect that you get this error?  Can you show how to get
the error starting from 'emacs -Q'?  Does doing 'M-:
(python-shell-prompt-set-calculated-regexps) RET' help?

> I'm just doing "ido-find-file".

From what buffer?
