Apparently fogbugz has their own nice stackexchange instance (I still wanted that for pharo).
And there is a nice feature request to list related bugs if you report one, something I have been missing for a while at the google issue tracker. And something I ran into a couple of times myself by not searching for other bugs first. so vote up! http://fogbugz.stackexchange.com/questions/5318/feature-request-discourage-duplicate-cases
