What happens:

record_extension WHERE (record_extension.tablename = 'article' AND

It confirms my suspicion, this is a call to a DBA driven delete of a 
parameter: It is first retrieved from the DB (that seems to succeed), but 
Midgard fails on the subsequent delete with a failed assertion.


Live long and prosper!
