Yes, I can confirm that this causes the parser to fail, I'm looking into it, 
thanks.

Actually, my test was flawed, { color: inherit } does work for me. I think what 
is causing your CSS to fail to parse is actually the font: shorthand property, 
which our parser expands into all constituent parts. This is an issue I've 
known about for a while. I'll set this bug to track dealing with it.

Just to clarify, this was fixed in r270 and Jan says it will be in the release 
coming out soon.

Thanks for looking into the issue.

I've manually split the the font: but still don't see minification. This is 
also true, however, if I remove the color: inherit which I originally suspected 
as the culprit, so perhaps something else is playing a hand here.

I'll wait for the next .deb release and see how I get on; fingers crossed!

Alright, the issue is "list-style-type: none", none is not being accepted as a 
valid value here, but it is valid (See 
http://www.w3.org/TR/CSS2/generate.html#list-style), so I'm filing this as a 
new bug 128.
