container:delete not working consistently after crash

container:delete does not work as expected.

1. I had a Fuse instance which had hung for some reason.
2. I killed the process and started again.
3. Then I did the fabric:create with clean option.
4. I noticed that it picked up a child container created before.
5. I tried to delete the container as shown below and recreate.
6. Delete succeeds, but creating it again fails.

P.S. I couldn't find the option to log this bug which happens under Fuse 6.2.1. standard edition.(no option for this on the menu)

For me once deleted, references to the old container should be cleared and creating the container again should work.
