=== Steps ===
i. I downloaded http://ftp.gnu.org/gnu/emacs/windows/emacs-24.5-bin-i686-mingw32.zip.
ii. I extracted zip file to temp folder; completely unmodified.
iii. I opened an MSYS shell and cd'd into the temp/bin folder.
iv. I ran ./emacs.exe -Q.
v. I C-x C-f and call the new file temp.py
vi. I type the following up UNTIL % - which represents the cursor position:
import re as myre
var = [
%
vii. I then press TAB and get the minibuffer message: Wrong type argument: number-or-marker-p, nil

Yes, reproducible in 25.0.50. `python-syntax-closing-paren-p' needs to
cater for the case that there is no syntax after point...

Perhaps something like this. Fabian?
