--text follows this line--

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 address@hidden mailing list, and to the gnu.emacs.bug news group.

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

================
(This is pasted from Emacs into thunderbird since I don't have Emacs set up to send mail).

When running gdb under Emacs, M-x gud-tooltip-mode works fine with
tooltips appearing as the mouse is moved over variables.

With the following in the .emacs file:-


(custom-set-variables
  ;; custom-set-variables was added by Custom.
  ;; If you edit it by hand, you could mess it up, so be careful.
  ;; Your init file should contain only one such instance.
  ;; If there is more than one, they won't work right.
 '(gud-tooltip-mode t)
 '(inhibit-startup-screen t))

.....Emacs and gdb are then started but nothing happens when the mouse is moved over variables.

Doing M-x gud-tooltip-mode results in a message that tooltips are now
disabled implying that they were previously enabled and also that the
.emacs file was read correctly.

Doing M-x gud-tooltip-mode produces a mesasage that tooltips are
again enabled and this time the tooltips do appear with the mouse over
variables.

So it looks as if the .emacs file "half works" in that it enables the
mode but not the tooltips!

(I didn't turn off the startup file since it is part of the bug).

If there's anything else I can do to help please ask.

=================

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/22.2/etc/DEBUG for instructions.
