[Bug-AUCTeX] 11.84; blank lines around \begin{abstract} with entcs.cls affect whether previewing works

[Joe Wells]

Dear AUCTeX and latex-preview gurus,

Reproduce the bug with the following two files.  The first is marked
“inline”, so you should see it; the second is marked “attachment”.

\documentclass{entcs}
\begin{document}
\begin{frontmatter}
\title{X}
% Bug goes away if this is a blank line.
\begin{abstract}
% Even worse things happen if above blank line is removed.
Math: $\Phi$.
\end{abstract}
\end{frontmatter}
Math: $\Phi$.
\end{document}
%%% Local Variables:
%%% mode: latex
%%% TeX-master: t
%%% End:

entcs.cls
Description: Text Data

The expected behavior is that C-c C-p C-b (preview-buffer) should
cause both of the math expressions to be previewed.  The buggy actual
behavior is that only the first one is previewed.  (In the more
complicated paper from which this example is derived, all of the
previews for the math material after the frontmatter environment do
end up showing up somewhere, all together.)

If the first commented line is replaced with a blank line, then
everything works.  If the blank line above the second comment is
removed, then things get even worse and previewing fails completely.

So basically, in this particular situation, the \begin{abstract} line
must be surrounded by blank lines.

Any ideas what the bug is?

Joe
