SSL Website showing unlocked padlock

When I visit an SSL based website with a clean profile:
https://www.americanexpress.com/ja-jp/

and then try to log in (click the button that says ログイン at the top right) - Orion loses trust in the SSL:

I can ignore this error and log in, and everything works just fine, but from then on, it loses trust in other trusted domains as well:

Also, I cannot click the "unlocked" padlock to inspect the certificates. I just enter the address bar in edit mode.

I would like to be able to inspect certificates, and the certificate handling should be improved to allow a complete chain of trust to be verified.

Version 0.99.128.2.1-beta (WebKit 619.1.11.111.2)

Strangely, I can't reproduce this issue - I see a valid certificate for the domain name in question:

You seem to be getting a different certificate, which, if that's what you were being served, isn't the right one for that domain (presumably).

Not able to reproduce.
