I'm using a Rails 2.3.10 stack with OmniAuth, Unicorn, and Nginx. We've noticed that during the callback phase from Salesforce OAuth2, an Internal Server Error is thrown.

I'm trying to get some clues as to where it's coming from. I don't think it's in our application code as no logging occurs during this error. It's definitely possible something in our stack is throwing the error.

The error page has "Internal Server Error" and nothing else. I haven't been able to get any clues from the headers or logs. However, the error occurs on our domain at the callback endpoint.

Any help would be great. Thanks guys.

I'm surprised I can't find this anywhere: I'm trying to make a custom mailto: link in SFDC that automatically bcc's the user's Email to Salesforce address:

mailto:{!Contact.email}?bcc={!$User.????}

How can I refer to this?
