# \listoffigures chokes on inline math delimiters in captions. What is going on?

I'm working on my thesis, and I've realized that, any time I try to use -type inline delimiters in captions, that pdflatex breaks. While I can weasel out of actually \needing\ math in my captions, it's very inconvenient. I'm pretty perplexed.

Here's a (relatively) minimal example that breaks for me:

\documentclass{uafthesis}

\usepackage{amsmath}
\usepackage{graphicx} % Graphics stuff

\begin{document}

\listoffigures

\begin{figure}[h]
\centering
\includegraphics[width=0.3\textwidth]{angle.png}
\caption{$$\theta$$}
\end{figure}

\end{document}


Here's a sample of the output:

! LaTeX Error: Bad math environment delimiter.

See the LaTeX manual or LaTeX Companion for explanation. Type H for immediate help. ...

l.1 ...k or to continue without it.}}}{2}

? ! Extra }, or forgotten \$. ...r to continue without it.}}

l.1 ...k or to continue without it.}}}{2}

?

Some things:

• uafthesis is the unofficial official document class for my university. It has been written mostly by physics grad students by hacking at other document classes. My fork is here.

• This only happens if I include amsmath.

• The minimal example and the resulting log file are gisted here.

I'm defending tomorrow, and I have to turn in my thesis pretty soon, so hopefully we can figure this out within a day or so! If not, I understand, and thanks anyway.

I asked irc://freenode.com/#latex, and they said to use the fixltx2e package, or alternately, to use dollar signs instead. Also learned that article has \listoffigures.
fixltx2e makes several other things robust as well. See this question. –  TH. Apr 4 '11 at 6:58
