I think #49 should have fixed this issue

[glennmatthews]

I think this issue is subtly different from #47 as fixed by #49, especially given that it's reported as present with version 1.4.0 of the importer. It's not clear to me from the initial report though whether the described steps-to-reproduce are without the separate objectchange data import (in which case the described behavior is expected) or whether we have an issue specifically when importing objectchange records as well.
