  <p>I've run into this before, but I've had no luck in diagnosing/solving it. It also shows up as a weird element in the page its linked to. </p>
  
  <p>Could someone help me understand the traceback? I'm sure it's something incredibly simple, but I know very little Ruby. I've tried removing/reinstalling Sass.</p>
