Yes, that's expected behavior. ;-)

With Rucksack, you can have as many cycles as you want in persistent
objects, but Rucksack won't attempt to detect cycles when serializing
objects that are 'outside Rucksack's control'.

The reason is that this is too expensive in general.  For circular
lists it's cheap and I suppose that could be added to Rucksack, but
I wouldn't want to add circularity detection for arbitrary data
structures.
