[Greg Couch]

I've added code to skip degenerate bild commands, so you should only get a warning, not a traceback. That change will appear in the next successful daily build. So please download the daily ChimeraX build tomorrow and confirm that this is fixed, _or_, send us the problematic bild file, and we'll confirm that it fixed with your data.

[Greg Couch]

No response. Assume the fix worked.
