Reporting bugs upstream

Hello, When I find a bug in fedora and it's obviously a bug upstream I report it there. But do we have to report them in fedora bugzilla too and reference the upstream bugreport? So if an other users files a bugreport for the same bug and doesn't check upstream maintainer of the module know it's already filed upstream. Or do we have to notify the maintainer in other way? I've searched the fedora wiki for this but I can't find any information about this. thanks, Bart -- Bart Vanbrabant <bart.vanbrabant(a)zoeloelip.be&gt; PGP fingerprint: 093C BB84 17F6 3AA6 6D5E FC4F 84E1 FED1 E426 64D1
