ColladaLoader Unable to add material

When loading a model exported by Blender I get a lot (in the hundrets) of warnings like this:

[Wrn] [ColladaLoader.cc:1747] Unable to add material[Color_243_6379-material]
[Wrn] [ColladaLoader.cc:1747] Unable to add material[Color_243_6453-material]
[Wrn] [ColladaLoader.cc:1747] Unable to add material[Color_243_6103-material]

This appears to slow down loading of the model as it takes a couple of minutes (the model is rather big tough 70 MB).

The model is a collada file.

In the model I can see a color library:

    <material id="Color_242-material" name="Color_242">
      <instance_effect url="#Color_242-effect"/>

The color effect is embedded in the very same collada file.

    <effect id="Color_242-effect">
        <technique sid="common">
              <color sid="emission">0 0 0 1</color>
              <color sid="ambient">1 1 1 1</color>
              <color sid="diffuse">0.0864 0.0864 0.1488 1</color>
              <color sid="specular">0.25 0.25 0.25 1</color>
              <float sid="shininess">255</float>
          <float sid="index_of_refraction">1</float>

So my questions:

1.) Can searching for the material slow down loading 2.) Does anybody see the mistake I did? Can we get the material get loaded? Where sould they be? 3.) Can I force ColladaLoadar to ignore the material information?

1) Searching for the material might slow down the loading a bit. You could try profiling the code. 2) We would need to see the complete DAE file. 3) You can't force the collada loader to ignore the material information.
