[Exim] exim4 segfaults with bad forward file data

I'm not sure if it this counts as a bug or just user error..

If exim4 is given an exim3 (or possibly older) style config file which
allowed

file = .forward

in the userforward router

it segfaults. I fully realise that this will not ever happen to most
people but should exim point out the error rather than falling over?

N.B. This is not the fault of the convert4r4 script which had been applied
