Error when computing automorphisms of simple orthogonal groups

[savask]

Observed behaviour

gap> G := PrimitiveGroup(119, 1);
O-(8, 2)
gap> S := SymmetricGroup(119);
Sym( [ 1 .. 119 ] )
gap> IsSubgroup(S, G);
true
gap> N := Normalizer(S, G);;
gap> StructureDescription(N);
"O-(8,2)"
gap> Index(N, G);
1
gap> T := TwoClosure(G);
<permutation group with 32 generators>
gap> StructureDescription(T);
"O-(8,2) : C2"
gap> Index(T, G);
2

Expected behaviour

G is a subgroup of index 2 in T, so T must lie in the normalizer N.

NormalizerPermGroup outputs a correct answer:

gap> N2 := NormalizerPermGroup(S, G);;
gap> Index(N2, G);
2

[Dear "savask", Would you be willing to tell us your name and affiliation? I find it very awkward when working with people whose only identification is an anonymous handle. Thank you (Alexander Hulpke, Colorado State University)]

As for the bug, the issue ultimately is that GAP believes the group has no outer automorphisms. This stems from the table on the top of page xvi in the ATLAS, which calculates values d=1, f=1, g=1 and thus no automorphisms.
This is clearly wrong, but I need to find out what exactly the error is here (is the table wrong only for characteristic 2, or always) I will see to provide at least a workaround for the issue.
