Comment 2 for bug 1266874

As an example of package that does have tags upstream, but appears without tags in the context, take gimp.
Local database has no tag for gimp, but http://debtags.debian.net/edit/gimp shows actual tags for it.

For the sake of completeness, the debtags database is so small that it can be pasted here.
