The best place is upstream if you think that's an upstream bug. Most of the time we simply copy them to their bug tracker. If you think a bug should be fixed for the next version of Ubuntu though you should open a bug on launchpad
-- CRASH : Setting up a view in the todo https://launchpad.net/bugs/73555 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
