Try out another branch

[hulpke]

Just to see what is hapening, this is another branch, freshly branched off master, with the cherry-picked changes. It is only intended to trigger the travis-tests to see whether they also cause an error.

I think that the actuall error is in

########> Diff in /home/travis/build/gap-system/gap/tst/testinstall/opers/Comp\
lementClassesRepresentatives.tst:24
# Input is:
N := Group((6,7,8),(6,7,8,9,10));; ConjugacyClassesSubgroups(G);;
# Expected output:
# But found:
Error, no method found! For debugging hints type ?Recovery from NoMethodFound
The 1st argument is 'fail' which might point to an earlier problem
Error, no 1st choice method found for `SubgroupsOrbitsAndNormalizers' on 3 arg\
\
uments
########

and the 2nd is just caused by using some other N instead, since the previous command failed:

########> Diff in /home/travis/build/gap-system/gap/tst/testinstall/opers/Comp\
lementClassesRepresentatives.tst:25
# Input is:
Set(ComplementClassesRepresentatives(G, N), H -> H^G)=Set([ Group([ (1,2,5)(3,\
4)(6,7), (1,4)(2,5,3)(6,7) ])^G, Group([ (2,5)(7,8), (1,3,5,4)(6,10,9,7) ])^G,\
 Group([ (2,3,4)(6,8,10), (1,2)(3,5,4)(6,10,7)(8,9) ])^G ]);
# Expected output:
true
# But found:
Error, cannot compute complements if both N and G/N are nonsolvable
########

This does not explain why it's here and not in the other tests though.

This causes the same errors, so no no need to pursue.
