System Information
Win 10 64bit

Blender Version
Broken: 2.78a e8299c9

The Collada exporter is capable of export empty meshes but cannot (re)import them.

When a Collada file is exported from this scene empty.blend the empty mesh is also written to the Collada file like "<float_array id="empty-mesh-positions-array" count="0"/>" is present (empty.dae) but the empty mesh and object is ignored when importing the Collada file.

Assigning to @gaiaclary.

The importer has an explicit check to skip such meshes, probably it's fine to just remove that? I don't see a reason to consider this an error.

    if (mesh->getPositions().empty()) {
        fprintf(stderr, "ERROR: Mesh %s has no vertices.\n", name.c_str());
        return false;
    }

Hi, Daniel;

Thanks for reporting!
Indeed it makes sense to allow the import of empty meshes as well.
