Comment 5 for bug 1103002

Dolph, the commit I'm talking about is https://review.openstack.org/#/c/10584/, which is weird because 2048 bit (!) keys should be unrelated to a 1024 char (!) error.

Initially I started with a revert of this commit and cleaned up the stuff further, but haven't gotten around pushing it for review. I can do that by the end of this week I think.
