Yep, that looks like a bug. 

TL;DR:

The session attribute is removed from images dictionaries in the
to_dict method[0] and it looks like that's happening before tags are
loaded, which means that it won't be possible to load them since
there's no session and sqlalchemy gets really mad. :D

Please, file a bug for this.

Thanks a lot.
