That only seems to bury the root cause because router_ids shouldn't be none
in this case with the reference L3 plugin.
The ML2 plugin calls disassociate_floatingips with do_notify set to False
so it should always be at least an empty set coming back.
Which L3 plugin were you using? Perhaps the implementation of
disassociate_floatingips was incorrect.
