I tried to use ubuntu-bug to report a problem with the 11.04 upgrade (https://bugs.launchpad.net/ubuntu/+bug/774359) as directed here (https://help.ubuntu.com/community/ReportingBugs). When I select the "Other Problem" kind of problem, I get an error dialog stating "You need to specify a package or a PID. See --help for for more information." That GUI is really flawed. If the "Other Problem" is really going to be left as a fatal choice, then it should at least make it clear that you want someone to run the command "ubuntu-bug --help". However, consider how one should proceed if they want to report a bug in the Ubuntu upgrade? I don't know what package or PID I would even give, and I can express that very condition on the web submission form, but this GUI gives me no way to do that.
