zip container with Title.xhtml file and Impressum.svg file of an epup file

An error occured when I open a epub file with Calibre Ebook Reader. 
I made a bug report to Calibre. Calibre answered:

"This is caused by a bug in QtWebKit, the HTML rendering library used by calibre. You should open a bug report for them. Apparently QtWebKit cannot handle SVG files with embedded fonts. In your bug report attach the  Title.xhtml and Impressum.svg files."

Please follow this to report bugs on QtWebKit: http://trac.webkit.org/wiki/QtWebKitBugs

If I understand the bug correctly, when I open Title.xhtml, the second image does not have the text shown?

It looks for me like the svg image handler is rendering the svg instead of WebKit. This is because the svg is inserted as <img> tag (non standard by the way :)).

I think that could work if they did not ship the SVG image reader plugin with their application. You can tell them to test that.

You should be able to work around the issue in your document by using <embed> instead of <img> to integrate SVG. I do not know if epub support <embed>?

This bug is valid, but there is probably not much we can do about it. Since it is loaded from disk, and with the image tag, WebKit does not know about the mimetype and it make sense to pass that to the image reader.
