Comment 1 for bug 1848266

Hi,

This actually makes a lot sense since you do not have gluon final state for you re-weighting definition. So indeed you do not have any matrix-element with which to re-weight and therefore this lead to a crash.

Now I guess that in this particular case, the correct behavior is to set the weight of all those events to zero. I do not want to have this as the default behavior since this is the sign of a bug in 99% of the case. So I will add a flag in 2.6.7 in order to allow to set the weight to 0.

the way to set the flag would be
change allow_missing_finalstate True

Cheers,

Olivier
