Comment 2 for bug 1804621

See commit https://github.com/yade/trunk/commit/7c60d78bd9badfa174fb79a82af7b119abf81d5d. It fixes the example in the above and the related Launchpad question (I guess, since there was no MWE therein ;-) ).

There are also several uses of aabb tuple stuff in /py/pack/_packPredicates.cpp which is untouched for now and requires more time to be looked at. It is not mandatory things are broken there.
