Fix in an issue in the call forwarding handling code that was causing crashes
on every call into a queue.  I'm not entirely sure about the logic in this part
of the code, so I want to look at it some more tomorrow.  However, this makes
it safe and keeps it from crashing.

(closes issue #11486, reported by adamg, patched by me)
