1365	Bad geometry can crash graphics on ribbon generation	Tristan Croll	Eric Pettersen	"Arising out of working through CASP assessments... one model had a residue (the first, but I don't think that should actually make a difference) in which all the coordinates were zero. This crashes dssp and, by extension, the whole graphics loop on generating the cartoon when first loading the model.

I think the _create_ribbon_graphics code needs to catch the ValueError coming out of get_polymer_spline and do something intelligent, e.g. stopping the ribbon"	defect	closed	moderate		Graphics		fixed		Tom Goddard Conrad Huang				all	ChimeraX
