I just completed a database switch with Streams (uses AQ underneath) and had also a lot of weird problems with propagation. And the problem was database domain name, one database had domain name part of global name and the other database did not. After removing domain name from the destination databases global_name, propagation worked.

select * from global_name;

Just a simple thing to check, I'm not sure how relevant it is in the current case.
