Well that's the problem. There is no guarantee that there is an exchange rate in the pricedb. So, we can't get an exchange for shares with no pricedb, but the report should still provide information, isntead of just crashing. So I'm getting values for shares fromt he txns AND the pricedb and using whichever is most relevant. I guess that in a multi-commodity situation we have to fall back on the pricedb and gracefully handle it if there is none.
