 Under different circumstances I think that such a position would be
well justified. It may certainly be not worth fixing unimportant bugs
with fully known behaviour.

connection between small forces and reading the wavefunction file. Thus
the condition is likely to happen in other cases, where the forces are
not small. It is just a matter of time. Such sightings will definitely
confirm that the present issue is a "real" bug, and not just a
