Testing for parent window protocol in Opera

I am trying to find out the protocol used by a parent window in a child window. If I use window.opener.location.protocol, it works in everything (IE8, FF3.5.5, Safari4.0.3, Chrome4) except Opera. In opera i get:

message: Security error: attempted to read protected variable 'protocol'

This used to work fine in Opera, but I guess they changed it. I am using Opera 10.10. Is there any way to test for the protocol, or even determine if the parent window is the same location and protocol as the child?

You should only get the error when the protocols are different.

In other words:

var isParentSecure;
try {
    isParentSecure = window.opener.location.protocol === 'https';
catch(e) { isParentSecure = window.location.protocol !== 'https'; }

I haven't actually tested this.
