you can reproduce this error even without going through the html repr: repr(time_objs[:0]) and time_objs[:0].calendar raise the same error (but with a much shorter traceback).

To fix that, I wonder if we should either return None (since we can't infer the calendar from an empty array) or somehow cache the calendar (and all other dynamically inferred properties, if there are others) on creation / modification of the CFTimeIndex object.
