There is (git from a couple of days ago) a problem with referring to
equations containing an underscore in the label, I am fairly sure it was
allowed before, e.g.:
--8<---------------cut here---------------start------------->8---
#+LABEL: Equation:new_eq
\begin{equation}
x=\sqrt{b}
\end{equation}
Referring to an equation with an underscore: \ref{Equation:new_eq}
--8<---------------cut here---------------end--------------->8---
I get a libreoffice popup:
"Read Error. Format error discovered in the file in sub-document
content.xmlat 2236,92(row,col)."
I think it was many of these errors that caused the crash.

Crikey! That's quite a regexp. I think the only consideration is
whether you want it to be consistent with pdf export. Taking
consistency to an extreme could lead to a new #+begin_equation block
(<-- I haven't thought this through at all). Having said that I am
happy with the way it works at the moment.

Actually I have changed my mind, it does look better like that, it is
just that is was different behaviour to what happened before.
