Broken? Can't edit pages

[jorgtron]

I get the error message "Error updating page" when saving an edited page after latest Discourse update

@LeoMcA can you confirm the bug?

I get the error when I add CSS, if I only add body content saving works. Might be something do with css processing? Workaround I've used for now: Add inline CSS to tags in the body text.
