[GAP Forum] normalizer of the identity symmetric group

[Anvita]

Dear Forum,

This is probably trivial again,
but still I thought I should report it.

All is fine when I do the following:
------------------------
gap> G:=Group(());
Group(())
gap> N:=Normalizer(G,G);
Group(())
gap>
------------------------

However, a similar program makes GAP break:
-----------------------------------------------------------------------------
gap> S:=SymmetricGroup(1);
Sym( [  ] )
gap> N:=Normalizer(S,S);
Error, usage: Group(<gen>,...), Group(<gens>), Group(<gens>,<id>) called from
Group( pg ) called from
NormalizerParentSA( G, U ) called from
oper( super, sub ) called from
<function>( <arguments> ) called from read-eval-loop
Entering break read-eval-print loop ...
you can 'quit;' to quit to outer loop, or
you can 'return;' to continue
brk>
-----------------------------------------------------------------------------

Why?
