I found a similar issue with a collada file exported from threejs crashing blender. Attached is the exported dae file and corresponding png texture image.

That's great that this got fixed. I'm not sure how useful backward compatibility would be, unless someone was manually editing Collada files to get them into Blender properly., but it's a nice safety net to have just in case.
