C++ Broker QMF Exchange byte statistics don't seem to be being updated

Hey all,
I think that there's a problem with the Exchange Management Object's
byte statistics:
byteReceives, byteDrops, byteRoutes

I was doing a bit of refactoring of the QMF GUI and I noticed this.

The msg... statistics seem to be fine.

I couldn't say when this behaviour was introduced, but I'm pretty sure
that it would be fairly recent 'cause I reckon I'd have noticed.

I'm looking at a C++ broker built from trunk last weekend.

Is this my imagination? Have I missed something? Or has a bug crept in?

Cheers,
Frase
