It sounds like the data about this XML snippet is still inconclusive.

- Jon Stevens reports that if you change the extension to .css, it works
- Matt, in addition to using Jon's fix to the fix, you needed to increment
the version to fix the broken mime-type

So it's possible the XML snippet might be a red herring and it's something
in the deployment/version incrementing mechanism that fixes something about
the file being in a bad state.

Does anyone else have anything to report?
