Description of problem:
If you clone a repo ( say you are cloning repoY from repoX) and if you delete repoY while getting cloned, it deletes repoY but the cloning continues. If you watch the log you can see that and finally see tracebacks on createrepo 

To take it another step further

1. Clone repoY from repoX
2. Delete repoY while the clone is running.
3. Now clone repoY from repoX (note the same name)
4. Notcie that errors



root@preethi ~]# pulp-admin repo clone --id=f15 --clone_id=f15-clone1 --feed=parent --filter=filter-black -F
