Andi,

I already take a look where is the problem.

In fact B&W tool work fine until you don't touch Curves settings. It's due to a
wrong translation between 8<->16bits curves api introduced with versionning
feature. BQM don't care about versionning, but implementation is wrong as well.
It's a side effect.

There is already a report about this problem here :

Ok... it seems to work better somehow when not using linear curves.

Yes, it seems to work in the first place, but when you change the curve type to
"free", it is broken. Changing the type back to "linear" doesn't seem to help.
