Please create the log in append mode, there are lines clobbering each other in there. Also, your log doesn't have the same error MestreLion's does, so there could be more than one bug here.
His appears to be loading zone.msn.com, which doesn't give a blank page. He's referring to the inability to login, which is the same bug you're (likely) referring to.
MestreLion, please file a separate bug for that. This bug is solely for hotmail.com giving a blank page.
