Thorsten Scherler commented on FOR-829:
---------------------------------------

Our project.svg contains something like:
<g filter="url(#shadowFilter)" fill="url(#gradient)">
    <text x="100%" y="60%" style="font-size:24pt; font-family:Verdana ; 
text-anchor: end" >
    <for:project-name />
    </text>
  </g>

<for:project-name /> is where the "magic" and dependency to skinconf is created.

The problem lies in the core resource.xmap:
    <map:resource name="pipe-transformed-svg2png-resource">
<!-- here we create a dependency on skinconf.xml-->
      <map:call resource="generate-transformed-resource">
        <map:parameter name="path" value="{path}" />
      </map:call>
<!-- this dependency get used in the next step -->
      <map:call resource="transform-project2text"/>
      <map:serialize type="svg2png" />
    </map:resource>

If you remove the skinconf.xml from your project then the above will throw an 
error like:
