Mvc 4 bundling and base64 svg images

Question

I've been experiencing a problem with the Mvc4 bundling&minification feature when using embedded base64 svg images in the css.

Lets say I have a css rule like this:

url("data:image/svg+xml;base64,PD94...<snip>...")

This works fine when bundling and minification is disabled. However, when it is enabled, that rule gets rewritten like this:

url("/content/style/data:image/svg+xml;base64,PD94...<snip>...")

Breaking the url, since it's not a real URL but an embedded base64 image.

Anyone knows how to fix this, beside moving SVG images in standalone files?

Thanks.

It was just a bug on DotLess. We updated the nuget package and the problem went away.
