That's the cause of the problem: it should say nil instead.

Can you step through framep-on-display in that case and tell what does
each of the expressions in 'or' there yield for that frame?  That is,
each one of these:

  (terminal-live-p ":0.0")
  (framep ":0.0")
  (frames-on-display-list ":0.0")

My bet is that the 3rd one produces the bad result.

Thanks.
