Attachment: patch

The expection is raised because we're asking for a non existent tab.
We receive a "document start" before creating the first tab, which is probably what need to be really fixed.

Sounds like this is the same kinda error we see on XUL fennec when the "about:blank" page of a new tab fires off an event of two.

Wonder if this _is_ the case and if so, could we stop sending the messaging in JS?
