Just press Pause button on the firebug panel (on the left-top corner of it, two yellow vertical lines, when Script tab selected) - and it will stops at first JS string.

I suggest you just to insert alert()'s in the suspicious places - after some iterations you will found exactly string you need (where error occurs).
