I am preparing the 4.51 release. One of the fixes is this:

PH/34 Change 4.50/80 broke Exim in that it could no longer handle cases where 
      the uid or gid is negative. A case of a negative gid caused this to be
      noticed. The fix allows for either to be negative.                   

It looks like that is what caught you (see the "-1" above). The
candidate code for 4.51 is available in a snapshot:

Alternatively, the patch (that was sent by a user) is below.
