You mean AGILe rather than Rivet, I guess... there is nothing do with
Rivet going on in that command.

I've not been aware of that problem so far, but I've reproduced it on
lxplus5 with a fresh AGILe 1.1.6 installation, so it's certainly
genuine. I don't know anything about HW diboson setup: do e.g. any extra
flags need to be set? And does this work fine through the Athena
Herwig_i interface?
