AttributeError raised on invalid data URI in sanitizer #188
Description
While trying to sanitize u'<html><body><audio controls="" src="data:foobar"></audio></body></html>'
I get an AttributeError exception In HTMLSanitizerMixin line 218

216: if not m:
217: del attrs[attr]
218: if m.group('content_type') not in self.allowed_content_types:
del attrs[attr]Line 215 returns None , but in line 218 m is assumed to be None
