I am getting the following error: {{{ ValueError: The file 'netjsongraph/css/lib/""images/ui-icons_555555_256x240.png""' could not be found with . }}} The peculiar thing to notice is the name of the missing file contains {{{ "" }}}. Initially I thought it might me an error in the CSS, but even after removing all CSS properties using {{{ url() }}} functions, the error was still there. The error disappeared only after I removed the comment in the CSS file which contained {{{ url(%22images%2Fui-icons_555555_256x240.png%22) }}} as a parameter to some URL. The {{{ post_process }}} should not try to make substitutions for {{{ url }}} keyword inside comments. Since it pattern matching is used to make substitutions, it will be better to process files without comments for pattern matching.
