Sass // @media all and (... fails

[Google Code Exporter]

What steps will reproduce the problem?

1. Create this mixin

@mixin opera_test {
  background: green;

  @media all and (-webkit-min-device-pixel-ratio:10000), not all and (-webkit-min-device-pixel-ratio:0) {           
    & {
      background: red;      
    }       
  }         
}

2. Use it

body {
  @include opera_test;
}   

3. View the css output

Actual output:

body {
  background: green;
  @media and {  body {  background: red;}}


}

Expected output:

body {
  background: green;
}

@media all and (-webkit-min-device-pixel-ratio:10000), not all and 
(-webkit-min-device-pixel-ratio:0) {            
  body {
    background: red;        
  }     
}
