self_see_filter not working with meshes [closed]

edit

For me, the self_see_filter seems to only work with primitives like boxes and not with .stl or .dae meshes. The robot model I use otherwise works perfectly fine in gazebo and rviz (specifically with using the mesh-based collision geometry), but the self_see_filter will always report

[ERROR] [1332881330.084931304]: Mesh asset has no faces
[ERROR] [1332881330.085950708]: Unable to construct collision shape for link 'top_box_link'

[ERROR] [1332881330.092628927]: No valid frames have been passed into the self filter.

If I substitute the collision mesh geometry with a primitive like a box, the filter does not complain. Does anyone have an idea why the filter is so picky with my mesh-based collision geometry? I'm on Ubuntu Natty/64Bit/Electric from .debs .
