Comment:
The patch attached to #8734 indeed fixes this problem. However there are
simpler solutions, and I'm not convinced that #8734 is necessary, given
that #7377 could solve this in a much cleaner way. Also see the discussion
linked from comment:3:ticket:8734:

In particular, Robert Dodier's suggestion to apply this patch to maxima:

I can confirm that adding these lines to
`$SAGE_LOCAL/share/maxima/5.20.1/share/contrib/Zeilberger/testZeilberger.mac`
solves this issue.
Perhaps this patch is already in a more recent version of maxima?
