Replying to [comment:2 cremona]:
> This will be possible to fix once I (or someone) have eventually
implemented heights of points over number fields, as I promised to do in
trac #360 !
I am not sure that using heights is the best way to get independence if
you are doing a 2-descent anyway. The easier thing to do would be to just
report back a set of points that minimally generate the 2-selmer group (or
at least minimally generate the part of the 2-selmer group generated by
the found points)
The only thing you'd miss that way would be if one finds generators for an
even index 2 subgroup of the full Mordell-Weil group. I think it's highly
unlikely that that would happen.
