Description of problem:
On Satellite 5.6.0 with Oracle DB backend there is ISE when you attempt to add Red Hat errata to custom channel.


Version-Release number of selected component (if applicable):
spacewalk-schema-2.0.2-13.el6sat.noarch
spacewalk-java-2.0.2-50.el6sat.noarch


How reproducible:
always on one system

Steps to Reproduce:
I'm not perfectly clear if this is the case of one specific system or all Satellite deployments, but this is what I have done:
1. Channels -> Manage Software Channels -> <some_custom_channel>
   -> Errata -> Add -> Add Red Hat Errata


Actual results:
ISE
