[Evolution] message filters not working

["Hegge, Johnathan" <Johnathan Hegge bluecoat com>]

2.12.2 on Fedora 8 against Exchange

All message filters defined are failing to act.  I've tried removing and
recreating the filters, no luck.  

I've run in the foreground and with --debug on, no messages relevant.  

I'm stumped.  The filters worked properly in Fedora 7's version.  

Any ideas?
