I have to admit that I don't understand the reason for the coding cookie
at all -- we bind coding-system-for-write to utf-8 before writing the
temp file anyway, and on the Python side, we specify the coding system
explicitly there, too.
But in case it does have an effect, I haven't removed it altogether, but
instead made the C-c C-e command avoid outputting it, which fixes the
problem. C-M-x, probably a more important command, is not affected by
the cookie one way or another (since it's just side-effecting), so I've
left it alone there.
