Description
The following bug report has been submitted: Platform: Linux-3.10.0-957.12.2.el7.x86_64-x86_64-with-centos-7.6.1810-Core ChimeraX Version: 0.91 (2019-11-28) Description This has to do with my ongoing efforts in making Clipper save/restore capable, and the trigger is certainly my own fault. I'm most of the way, but right now when I save a model with a cryo-EM map controlled by Clipper and then restore, I end up with an unparented Surface instance as model #2. Closing the restored model/map also closes the Surface, but borks the session with the string of "TypeError: object of type 'NoneType' has no len()" messages you see here - looks like ChimeraX is still trying to draw something (the Surface?) after its _delete_geometry() has been called. Will work out what I'm doing wrong - but would it be preferable to catch and gracefully handle this situation?
