The 'minor' field should be removed. Its description is inaccurate and most people won't file 'minor' bugs, i imagine.
Well, I myself do sometime report minor problems :) I would rather suggest hiding any severity above "normal" in the guided form. My observation is some users tend to abuse it and choose exaggerated severity when creating reports, probably with the (wrong) assumption that assigning a higher severity will increase the chance of it being taken of.
Thank you for the bug report. As this report hasn't seen any changes in 5 years or more, we ask if you can please confirm that the issue still persists. If this bug is no longer persisting or relevant please change the status to resolved.
