Comment 5 for bug 285746

In the meantime, perhaps the message in the Cruft Remover window could be changed from "This application helps you to get rid of cruft" to something clearer along the lines of "This application helps you to identify and remove packages that might no longer be necessary. WARNING: it is not currently possible to tell the difference between obsolete Ubuntu packages and third-party packages that you installed yourself."

(The existing message is rather unhelpful in any case -- "cruft" is hacker jargon that will confuse many users, and should not be used without explanation.)

Even if it's too late to change this in all the translations, just doing this in English would be better than nothing.
