MALFORMED Query when trying to execute a query with OUTER JOINs which only contains elements from JOINed source

If you're executing a query like this:

select PrimaryBusinessUnit, sum(oli.totalPrice)
from general.salesforce.Opportunity o left outer join general.salesforce.OpportunityLineItem oli ON oli.OpportunityId = o.id,
general.salesforce.PricebookEntry pbe, general.salesforce.Product2 p
where (PricebookEntryId = pbe.Id) AND (p.Id = Product2Id)
and isClosed=true
and isWon = true
and CloseDate > '2008-03-01'
and accountId = '00130000009SwiLAAS'
group by PrimaryBusinessUnit

you end up with a MALFORMED_QUERY exception.
