The Moblin bugzilla (and maybe others) has an interesting feature: It has a "file new bug for <product>" link at the end of a page when you search for bugs in <product>. If a developer wants to make sure that users actually read existing bugs reports before filing new ones, linking directly to the query (=the search results) in the bugtracker field wouldn't, IMHO, not only be acceptable, but even better than directly linking to the "enter new bug" form. what's your opinion?
