bug#8097: 23.1; ECB, info, and customization

[Joe Miklojcik <jfm3@jfm3.org>]

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 bug-gnu-emacs@gnu.org 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:

1) Start a fresh
   emacs -Q
   Load cl, ecb, cedet, semantic.

2) M-x ecb-activate

3) Observe you are now viewing info documentation which tells you to
   M-x customize-option RET ecb-source-path RET
   do so.

4) Observe the empty buffer you so wanted to have that customize stuff
   in.

5) Kill the empty buffer with C-x k.

6) Observe you are now back in the info buffer, but that customize has
   put its output there.

7) Finally, there seems to be no simple way to tell ecb to not yoink
   you into *info* every time you ecb-activate (unless there's a
   customization option I'm not seeing?).

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/23.1/etc/DEBUG for instructions.
