It appears that the "form action =" line gets confused when there is a login failure and you end up on an https page. Here is what I did.
1) Go to main page. It is an http page not an https page.
2) See login block.
3) Check code for login block - it looks good!
4) Put in bad username and password combination.
5) Get directed to https:///home?destination=home
6) Check code for login block - it looks bad! /home?destination=home"
