[Bug-AUCTeX] preview-1.287; Preview (of equations) doesn't work with beamer

[Jisang Yoo]

When I press C-c C-p C-p to generate preview images of equations in a
beamer document, the preview images get placed in wrong places in the
buffer. The images are all bunched up at the end of "\end{frame}". I
could reproduce this behavior with the following small init file:

#+BEGIN_SRC elisp
  (setq debug-on-error t)
  (cua-mode 1)

  ;; Minimal config to make AUCTeX work on MS Windows
  (setq preview-image-type 'pnm)
  (defvar my-gs-exe-list (list "C:/Program Files/gs/gs9.06/bin/GSWIN32C.EXE"))
  (dolist (exe my-gs-exe-list)
    (if (file-exists-p exe)
        (setq preview-gs-command exe)))

  (setq package-load-list '((auctex t)))

  (package-initialize)
  (setq package-enable-at-startup nil)

  (require 'tex)

  ;; Open the minimal beamer document for test.
  (find-file "~/t/simple-beamer.tex")
#+END_SRC

and the following minimal beamer document:

#+BEGIN_SRC tex
  \documentclass{beamer}
  \begin{document}
  \begin{frame}
    The $a^2$ and $b^2$ and the end.
  \end{frame}
  \end{document}
#+END_SRC

Following is generated from M-x preview-report-bug (from the Emacs
session that used the minimal init file.)
