Migration from RHN to subscription manager caused a minor issue

I migrated my RHEL-6 (server) machine from classic RHN to subscription manager by following https://access.redhat.com/documentation/en-US/Red_Hat_Subscription_Management/1/html/MigratingRHN/index.html . All went fine, but as soon as the migration finished, I started seeing the following line in /var/log/messages:

abrt: detected unhandled Python exception

The above abrt line appears in /var/log/messages exactly every 2 minutes. No other lines are seen. No useful information to debug with. Other than that, the system has been running with no apparent issues.
