I am working on an ebook application with WebKit 3 (webkitgtk-3.0) on Elementaty OS Freya. epubs which have html display fine, however the new epub 3 with XHTML comes garbled with multi columns instead of paragraphs. I have attached screen shots of both. changing the mime type to "application/xhtml+xml" also does not resolve the XHTML content. Code at launchpad .
Appreciate any guidance on how to fix this.
