Yep, this bug is still actual. Resize, migration and so on does not work 
if original image is deleted. And 'I will never remove any public image' 
will not helps, because if user restore instance from snapshot and 
remove snapshot it will cause error too. That looks stupid in the light 
of (our) raw disk format, where 'base copy' just never used.

Error is harmless and can be fixed by

nova reset-state --active UUID
(optionally)
nova stop UUID
nova start UUID

But it's still annoying because user can not fix it own instance without 
administrator intervention.

We have plans to fix it for havana (it cause disturbance for as and 
inconvenience for our customers), but fix will not be accepted by 
upstream (they drops upstream support ASAP), so I think we should switch 
to old-style maillist based patch RFC.
