[OS X TeX] Package mathbbol 'crashes' LaTeX

[Markus S]

Hi,

using the package mathbbol and math mode in an environment like 
\section{} causes my LaTeX installation to go almost wild using 
TeXLive-2007 on OS X 10.4.10 (Intel). Example code is as follows:

\documentclass{report}
\usepackage{mathbbol}
\begin{document}
\section{Trying out math mode $a$}
\end{document}

The error message is huge, the .log file has almost 40000 lines, here 
is the beginning
(/usr/local/texlive/2007/texmf-dist/fonts/source/public/bbold/bbparams.mf
