This bug report will be sent to the Free Software Foundation,
not to your local site managers!
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 <at> 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.  If you can, give
a recipe starting from `emacs -Q':

Normally, nxml-mode automatically indents new lines the proper amount,
and re-indents after closing tags.

However, if nxml-slash-auto-complete-flag is set to true, completed tags
on new lines are not re-indented.

For instance, type the following:
<para>
This is a para.
</

The closing tag (</para>) is automatically completed, but the line is
not indented properly.

When the above-mentioned flag is true, / is mapped to
nxml-electric-slash. The following advice works around the problem:

(defadvice nxml-electric-slash (after nxml-electric-slash-indent activate) (funcall indent-line-function))

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'.
For information about debugging Emacs, please read the file
/usr/share/emacs/23.2/etc/DEBUG.

Subject: [PATCH] 23.2; nxml-mode Indentation Behavior
Date: Wed, 14 Jul 2010 11:51:56 +0800

We discussed a workaround on #emacs already. But in case somebody else
has this bug, this might help:

(defadvice nxml-electric-slash (after indentation-bug-workaround activate)
  ;; fixme - workaround for indentation bug, remove once fixed
  (funcall indent-line-function))

And here's a patch:

*** /usr/local/share/emacs/23.2/lisp/nxml/nxml-mode.el.gz
--- /tmp/buffer-content-33187GX
*************** on the line, reindent the line."

     (self-insert-command (prefix-numeric-value arg))
     (unless arg
!       (if nxml-slash-auto-complete-flag
         (if end-tag-p
             (condition-case err
                 (let ((start-tag-end
--- 1212,1218 ----

!             (insert ">")))
       (when (and end-tag-p at-indentation)
!         (nxml-indent-line))))))

 (defun nxml-balanced-close-start-tag-block ()
   "Close the start-tag before point with `>' and insert a balancing end-tag.

This seems to be working on the Emacs trunk, so I guess somebody already
made this change.
