collada files not visualized in Gazebo 1.9

edit

Hi all,

I have a robot using (collada) .dae files for visualization. Before Gazebo 1.9 they worked just fine, but after updating to 1.9 they do not show up anymore. (previously I used the version which came with ROS-fuerte, don't know the actual version number..)

Here are relevant parts of one of the files:
