[Eric Pettersen]

Don't know what happened, but the 'category' for the "Point signals" format (provided by the signal_viewer bundle) is an empty set instead of a string.

[Tom Goddard]

When I list the format which have category = set() instead of string I get Schrodinger Maestro and Structure factor MTZ. These are formats provided by uninstalled bundles. The SignalViewer bundle that Eric said in the previous comment had category set() is also a toolshed bundle not included in the daily builds.

So it appears that toolshed bundles that are not included in the ChimeraX build and not installed cause this error. This will effect everyone who gets a new builds and uses File / Open... so should be fixed soon.

[Conrad Huang]

Fixed in d1cafaf2d.

Code added to report formats supported by uninstalled bundles introduced this bug. Data formats can only belong to a single category, unlike tools or commands.
