Confirmed, probably the same root cause. When I brute= force override python-nav-end-of-statement like below, it doesn't happ= en any more.

(defun python-nav-end-of-statemen= t (&optional noend)

=C2=A0 (fo= rward-line 1))

The single quote and multiple lines in the docstring are nece= ssary for the repro. No extra newline at the end needed though.

JD, do you have a workaround for this? I may look into overriding python= -nav-end-of-defun until it's fixed. Any other ideas?
