Subject: 23.0.60; emacsclient -t inserts one char when pressing an arrow key
Date: Thu, 28 Aug 2008 21:06:59 +0200

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 <at> gnu.org mailing list.

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

1. Start emacs -Q
2. eval (server-start)
3. from a terminal, invoke emacsclient -t some-file
4. Press <left>, <right>, <up> or <down>

The first keypress of an arrow key after the emacsclient invokation
inserts one D, C, A or B.  The next press moves point as expected.  With
emacsclient -c this does not happen.

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/share/emacs/23.0.60/etc/DEBUG for instructions.

Thanks.  I can reproduce this too.  Do you know whether or not this
problem only appeared recently?

No, sorry.  Normally I use emacsclient -c all the time.  But since
nobody has reported it before, I'd say the problematic change shouldn't
be too old.

Bye,

Anyone have any idea what causes this bug?  I noticed that if you switch
to the X frame, then switch back to the terminal frame, the first arrow
key you enter into the terminal then behaves correctly.  Very strange.

I've checked in a fix.

I can confirm it works now.  Thanks a ton!
