Bug Description

The issue is with StoneageHTML and the cssutils package that it uses. The latest version cssutils 0.9.6b3 causes the problems. Pinning version cssutils=0.9.6b1 in the buildout fixes this.

This happens when you have added a style sheet (well, some css lines) in the composer. It can be tested simply by rendering the preview of the news letter. Using cssutils=0.9.6b1 indeed fixes it for me too. But that gives problems with some css lines; for example with this css it fails too:

   * {
    margin: 0;
    padding: 0;

Those lines are given to me by the local css guru, so I assume they are fine. :-)

Traceback is then this, apparently because '*' is not recognized by StoneageHTML as a selector:

Traceback (innermost last):
  Module ZPublisher.Publish, line 119, in publish

IndexError: list index out of range

Might it be a good idea to use stoneagehtml only when it works and just use the original html otherwise? So something like this:

html = method_to_render_original_html()
    html = stoneagehtml.compactify(html).decode('utf-8')
    logger.warn('Exception while compacting html with stoneagehtml; using original instead.')

I fixed this in revision 118433 and 118435 by adding a function 'compactify' in collective/dancing/ with the try/except, and using that instead of using stoneagehtml directly.
