I don't know how fix this bug because the problem is related to the parser (and 
it's a lot of complex!!!). I attach the CSS file that cause the problem. The 
minify is called without a config argument (non used to force the default 
configuration).

Fixed in version 2.0.2.1.

The expression parsing is more kind of temporary fix. There are no semicolor 
and right curly brace allowed in the expression value except if they are 
escaped in a string.

While right curly braces are allowed in expression values nobody should use 
them because they will break the css parsing of other browsers than IE. 

Semicolons are more of a problem as they are also allowed in a expression value 
and they can get used like in --> content: expression(Math.random();) <--. 
Semicolon used that way will break the parsing and i won't fix this in version 
2.x.

I will try to implement a stable expression value parser in version 3.x.
