Code review comment for lp:~yamahata/glance/lp802883

I think we all agreed that those fixes should go into glance tree.
But don't agree on how we should go for it.
(To be honest, I don't care of what is the right procedure in launchpad
as long as the changes are accepted)

So in order to make progress, I merged other two fixes into this branch
and marked the other two bug report invalid.
Now this branch includes all three fixes.
https://code.launchpad.net/~yamahata/glance/lp802883/+merge/66092
So all things to do is merge the branch into glance trunk.

If you want me to do other way, please tell me how/what I should do.
So I'll do so.
