Updating to OS X 10.10.2 broke Quick Look previews for HTML files

Known bug on Apple's Bug Radar as Bug # 19639311

10.10.2 quick look broken for HTML files

qlmanage -t <path_to_html_file> produces a small thumbnail of the HMTL file
qlmanage -p <path_to_html_file> just gives me a blank quicklook preview

This doesn't happen with a .jpg file I used as a control sample.
