Comment 10 for bug 1767187

Initially I wanted just to throw exemption, but than found out that must such cases are just invalid combinations of ware&tribe...

If you look at ware_descr.cc you can see multiple rows "return kInvalidWare" so the problem can be more widespread.... just going unnoticed...

I am not sure if tribedescr.wareindex is available while working in ware_descr.cc
