Docbuilder and auto-generated files

On some OS X 10.6 system, I noticed that suddenly the following changes appeared in my working repository:

doc/en/reference/misc/sagetex.rst

-Installing and using SageTeX
-============================

-SageTeX is a system for embedding computations and plots from Sage into
-LaTeX documents. It is included by default with Sage, so if you have
-installed Sage, you already have SageTeX. However, to get it to work,
-you need to make TeX aware of SageTeX. Instructions for that are in the
-"Make SageTeX known to TeX" section of the `Sage installation guide
-<http://sagemath.org/doc/installation/index.html>`_ (`this link
-<../../installation/index.html>`_ should take you to a local copy of the
-installation guide).

If this an autogenerated file, it should not be tracked by Mercurial. And also, what happened to this file, why did all content get removed?

This happened with sage-5.8.beta2, it is always reproducible (at least on this particular build), even when no source files have changed. The output of a make doc-html run can be found in doc.log.
