Incorrect minification of font-face if there is no space before the opening brace

[GoogleCodeExporter]

What version of CssMin are you using (source and/or build)?
3.0.1

What was the input stylesheet and/or configuration options?
@font-face{
    font-family: 'HelveticaNeueBoldCond';
    src: url('../css/fonts/helveticaneue-boldcond-webfont.eot');
    src: url('../css/fonts/helveticaneue-boldcond-webfont.eot?#iefix') format('embedded-opentype'),
        url('../css/fonts/helveticaneue-boldcond-webfont.woff') format('woff'),
        url('../css/fonts/helveticaneue-boldcond-webfont.ttf') format('truetype'),
        url('../css/fonts/helveticaneue-boldcond-webfont.svg#HelveticaNeueBoldCond') format('svg');
    font-weight: normal;
    font-style: normal;
}

#bg1{
    position:absolute;
    z-index:1;
}

What is the expected result?
@font-face{font-family:'HelveticaNeueBoldCond';src:url('../css/fonts/helveticane
ue-boldcond-webfont.eot');src:url('../css/fonts/helveticaneue-boldcond-webfont.e
ot?#iefix') format('embedded-opentype'), 
url('../css/fonts/helveticaneue-boldcond-webfont.woff') format('woff'), 
url('../css/fonts/helveticaneue-boldcond-webfont.ttf') format('truetype'), 
url('../css/fonts/helveticaneue-boldcond-webfont.svg#HelveticaNeueBoldCond') 
format('svg');font-weight:normal;font-style:normal}#bg1{position:absolute;z-inde
x:1}

And what is the actual result and/or error message?
@font-face{position:absolute;z-index:1}

Please provide any additional information below.

The code to test it : print_r(CssMin::minify($content));
The fix is to add a space after @font-face, like so :
@font-face {
    font-family: 'HelveticaNeueBoldCond';
...

p.s. and I have tried on the current latest version 3.0.1. But I cant fix mine 
with the "The fix is to add a space after @font-face" - that still doesnt solve 
my bug

There appears to be a problem with multipe @font-face declaration (where you 
use different font-weight/font-style combinations for different sources to make 
the browser pick the proper source).
cssmin seems to compact these into a single @font-face group (instead of 
keeping them separate (normal, bold, italic, bold-italic).

I'm having this bug with @font-face

@font-face{
    font-family: bebas;
    src: url(../fonts/BebasNeue.otf);
}
html,body{height:100%;}
body{background:black;}

result is
@font-face{height:100%}body{background:black}

This problem can be fixed by changing
https://code.google.com/p/cssmin/source/browse/trunk/source/parser/plugins/CssAt
FontFaceParserPlugin.php#50
From
return $index + 10;
to
return $index + 9;
