[2.0] folder-info file syntax change/broken?

<link rel="stylesheet" type="text/css" href="[[FOLDER]]/folder.css">

<div align="center">

<img src="[[FOLDER]]/header.jpg" width="100%">

</div>

The paths are translating like they used to:

[[FOLDER]]/folder.css becomes http://192.168.1.110:2202/ubooquity/comics/119?folderinfo=/folder.css but the file itself error 500s.

Is this a syntax change or an error?
