Thanks Vitalie

This is better.

I've been testing this change with ESS-20150827 from MELPA.  I think
the change clears up the problem almost entirely when I have just 2
frames open.  When I have 3 frames open, the tracebug finds various
frames from time to time.  It does not say "in" the first frame it
found.  I regard this as a price I have to pay for having the bad
habit of liking things in separate frames.

While trying to test various versions of ESS, I've come to some new
questions about installation and I'm going to write up a separate
question on that.
