The generated SVGs do not contain embedded fonts so I assume that you used --nofonts option. Embedding fonts is important to keep the accuracy/consistency of the file conversion.
Having said this I tried to convert the file without --nofonts and got similar output in Chrome. Please keep in mind that current state of SVG supportacross browsers is still quite weak and inconsistent (and pdf to svg converter implement various browser specific hack to go around limitations).

Although we could resolve the conversion issue, I just wanted to make sure that you are also aware of PDFNet WebViewer: http://www.pdftron.com/pdfnet/webviewer

PDFNet WebViewer is using HTML5 Canvas element to render PDF and can produce consistent output across different browsers and platforms (including mobile devices - e.g. iPad/iPhone, Android, etc).
The WebViewer HTML5 API also allows for complete viewer customization (http://www.pdftron.com/pdfnet/webviewer/demo/html5/doc/index.html) and extensions (e.g. with markup, forms, etc.).
