Our client uses a special number for identifiers in their
applications.  This number has no special meaning as far as
being recognized immediately by anybody (they call them 'A'
numbers -- its the letter 'A' followed by a 5 digit number).
 These identifiers are usually only known by the user.  So
we want to reuse these 'A' numbers for login purposes.  But
so that users can see who submitted the issue, we use the
real names for the labelprop.  As I stated originally, the
problem comes in with multi-links.  Roundup is putting the
label version in the field when it is displaying it.  When
the issue is committed (even without changes to the nosy
list), it still validates the nosy list.  Without my patch,
it errors off the label values that it placed in there.
