When I attach to an already-running emacs session with "emacsclient -t"
from an gnome-terminal window, the characters ">1;1609;0c" get inserted
into whatever buffer is first shown in the terminal.
That looks sort of like an ANSI escape sequence, so I imagine it's some
feature connected with term/xterm.el that isn't properly being handled
by Emacs in this case?
Thanks,
-Miles

Sort of, emacs sends an escape sequence and expects a reply back from
the terminal, it just does not wait long enough for the reply. I
increased the timeout in question. Does it work now?

I'd guess it comes from term/xterm.el's terminal-init-xterm where it does:
;; Try to turn on the modifyOtherKeys feature on modern xterms.
;; When it is turned on many more key bindings work: things like
;; C-. C-, etc.
;; To do that we need to find out if the current terminal supports
;; modifyOtherKeys. At this time only xterm does.
(let ((coding-system-for-read 'binary)
(chr nil)
(str nil))
;; Try to find out the type of terminal by sending a "Secondary
;; Device Attributes (DA)" query.
(send-string-to-terminal "\e[>0c")
;; The reply should be of the form: \e [ > NUMBER1 ; NUMBER2 ; NUMBER3 c
(when (equal (read-event nil nil 0.1) ?\e)
(when (equal (read-event nil nil 0.1) ?\[)
(while (not (equal (setq chr (read-event nil nil 0.1)) ?c))
(setq str (concat str (string chr))))
(when (string-match ">0;\\([0-9]+\\);0" str)
Maybe some other event (like switch-frame or some such) gets in the way?
Maybe C-h l can give us a clue?

I did C-h l, and it shows nothing unusual before the "ESC [ ..." (the
escape and bracket are there).
