Controller called twice

That's it? Then it's like I said, you are most likely getting two complete calls from the client, or at the server level. Those are the normal startup methods for a CodeIgniter controller.

If you were getting some kind of internal calling, you'd see a much longer stacktrace.

(You might want to throw it at the end of the method, to see if it is different.) Play around with it some more. You have all of the sources to CodeIgniter, so you can usually follow the function threads as you work. If I remember correctly, the "line number" doesn't always match up with the file name. You might have to be creative ;-)
