Yes, the bug is in mobi_html.py where we explicitly look for url( style pieces in the css but do not handle that case:

url_pattern = re.compile(br'''(url\(.*?\))''', re.IGNORECASE)

url_img_index_pattern = re.compile(br'''[('"]kindle:embed:([0-9|A-V]+)\?mime=image/[^\)]*["')]''', re.IGNORECASE)

font_index_pattern = re.compile(br'''[('"]kindle:embed:([0-9|A-V]+)["')]''', re.IGNORECASE)

url_css_index_pattern = re.compile(br'''kindle:flow:([0-9|A-V]+)\?mime=text/css[^\)]*''', re.IGNORECASE)

I will try to use your example see how to best to handle the missing case of a kindle:flow but with a mime=image/svg+xml.

I think we can easily handle it as a special case by adding a:

url_svg_image_pattern = re.compile(br'''kindle:flow:([0-9|A-V]+)\?mime=image/svg+xml[^\)]*''', re.IGNORECASE)

and then handling it just like we handle inlined css flow urls.

Thanks,
