I think the problem is that our ethernet code doesn't correctly handle devices that have no MAC address, and CTC devices don't have one because they aren't ethernet. But we treat them as ethernet in NM for convenience. Should be fixed upstream as: 696f655d7c7b605d0344aeb6ba4ff643cd46a5b4 ethernet: don't crash if device doesn't have a MAC address (rh #1029053)
I can confirm the fix from comment #12 fixes the issue, no crash with CTC adapter configured. Can we expect an updated build soon?
