Comment (by SimonKing):
Result: The error is raised in `__setitem__` and the iteration guard is
apparently invoked by `__getitem__`.
To be precise:
- The iteration context was entered by `__getitem__` with the arguments
`((<class 'sage.schemes.generic.divisor_group.DivisorGroup_curve'>, Affine
Curve over Complex Field with 53 bits of precision defined by -x^9 + y^2 -
x, Integer Ring), ())`, which looks like a `CachedRepresentation` to me.
- This iteration context is not yet exited when `__setitem__` is called
with the arguments `((<class 'sage.categories.groupoid.Groupoid'>, Complex
Field with 53 bits of precision), ())`
