23.0.50; error "Can't open mouse connection"

[Leo]

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the emacs-pretest-bug@gnu.org mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

M-x t-mouse-mode failed with:

Debugger entered--Lisp error: (error "Can't open mouse connection")
  signal(error ("Can't open mouse connection"))
  error("Can't open mouse connection")
  t-mouse-mode(toggle)
  call-interactively(t-mouse-mode)
  execute-extended-command(nil)
  call-interactively(execute-extended-command)

If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
/usr/local/packages/emacs/share/emacs/23.0.50/etc/DEBUG for instructions.

I suspect that you don't have the daemon process gpm running and debug-on-error
enabled.  What would you expect to happen?

That suspect is not true. I am using the mouse on Linux console just
fine.

Well I can't reproduce it on 23.0.50 which appears to be the trunk.  I can see
it, however, on the emacs-unicode-2 branch (23.0.0).  Maybe Kenichi Handa knows
how to fix it, otherwise it will have to wait until emacs-unicode-2 is merged
to the trunk.

BTW emacs-pretest-bug is just an alias for emacs-devel now so you don't
need to post to both groups.

Actually I can't seem to reproduce it on 23.0.0 now either.

In Linux Console, `emacs -nw -q' t-mouse works just fine. I can
highlights when mouse is over links etc.

Now if I start emacs in screen-256color and then in Linux console,
connect to it using "emacsclient -t", emacs crashes. I have managed to
obtain the following backtrace:

Hang on, we're not really communicating.  It's probably not helped by me
guessing the problem and then making a false assertion about emacs-unicode-2,
but is your original report about using screen-256color and emacsclient?
If so, you need to include these details in your report at the start.

I know very little about emacsclient but I do know that Stefan Monnier is
currently looking at emacsclient and gpm.  Perhaps the backtrace is meaningful
to him.

What default setup sends mail to both emacs-devel and emacs-pretest-bug?
For me, report-emacs-bug using a CVS version of Emacs only sends to
emacs-pretest-bug.

I do not understand the description of what you've done.  
Please state it again, in excruciating details, as if talking to a idiot.
Starting from "emacs -Q".
