Bug 4108 Catch cases when GetMember is generating errors

Fixed two calls where new interface was not used
Arguably new syntax allows more options than we require but it was not catching
error cases (when 0 or undef is passed). It also can now be called in ways
which would validly return multiple hits but explicitly does not
(nor does calling code expect this)
This patch should quieten the flood of errors
