mdlKISolid_checkBody will probably return an error for this solid...but not every solid that returns error will necessarily fail to return surface elements. It's also true that a completely valid body may not return good surface elements for every face as these sometimes are just approximations of a "foreign" surface type.
Determining to what extent a particular solid is "bad" is not an exact science. My experience is that you can't be too strict about this since there's a lot of mostly valid geometry with minor faults out there from various imported file formats and modeling operations.
This particular smart surface looks like it should have been covered by a plane, but instead it's been covered by a cylinder which strikes me as odd. The facetter also happens to returns 0 facets due to geometry errors for this body...
