Description of problem:

I have a system in beaker of which I am the owner and current user. When I attempt to provision the system when it is also loaned to me, the provisioning job scheduling does not complete and I get the error "object does not support item assignment"

Version-Release number of selected component (if applicable):
0.7.3

Every time - I tried returning the loaned system and verified that the provisioning job was scheduled. When I re-loaned the system to myself and attempted to schedule another provisioning job, I was presented with the same error.

Steps to Reproduce:
1. Loan a system (of which you are the owner and user) to yourself
2. schedule provisioning
  
Actual results:
"object does not support item assignment"


Expected results:
Successful scheduling of provisioning job
