I'm not sure if what I am seeing is related to this or another issue.

If I create a subscription for a publication that doesn't exist (yet) I 
see 'publication mypub does not exist" in the subscribers log

If I then create the publication on the publisher the error doesn't go 
away, the worker process keeps spinning with the same error.

If I then drop the subscription and recreate it it works.
