RHEVM: rhev-agentd broken ?

Hi

I've noticed that the applications_list that I have defined in /etc/rhev-agent.conf is not being displayed correctly in the Applications tab for my VM's.

The rhev-agent.log is showing the traceback below. Apparently unable to find a required vdsm file ?

I think this may have broken after I upgraded the manager to 3.0.7

Bug ?  Should I raise a support ticket ?
