Comment 3 for bug 1161078

Yes, list=true does fix the problem. Passing the security group id twice (e.g. --security_groups 057337f8-ea28-4aa8-b5d0-c35f9007d66f 057337f8-ea28-4aa8-b5d0-c35f9007d66f) also works around the problem.

However, a simple change will allow Quantum to handle it without any fuss. I'm just not cleared to submit it by our legal department so I have to find someone else here to do it for me. :-)
