You are shooting yourself in the foot by having that "%20" in the
header-line-format.  Percent sign is special in mode-line and
header-line formats: it indicates a %-construct, see the node
"%-Constructs" in the ELisp manual.

I fixed the code to avoid the infloop in this case, but you should fix
your code, because the result will not be what you probably expect.

Thanks.
