This was only happening without an active object. The "Operator Cheat Sheet" operator collects info about all operators, and as part of that executes the callbacks to create dynamic enums. The callback to enumerate the geometry operators (introduced in rB370d6e50252b) attribute domains depends on a context object. If this isn't available, we just have to return `DummyRNA_NULL_items`.
