I built master and I am not seeing the problem now, so this bug must
have been fixed.

[Both my analysis above and suggested fix seem to be wrong. I think
the problem was that my init file was requiring etags at some
point, which activated the error.
i.e. emacs --fg-daemon -Q -l etags
and  emacsclient -t
would have reproduced it and not the recipe i gave, sorry]
