Well, there was a try to register this media type in 1995/96, which has
not succeeded (nor failed). The original proponents are currently not
interested in another try.

However, the chemical/* media type has still been used and now we are in
the unfortunate situation, that this unregistered media type is used.
This is, why these mime types are not part of shared-mime-info and are
shipped in a separate package.

Which has already been done.

That's not the case here.

KDE and a few other packages are causing similar messages. So I prefer a
solution in update-mime-database, which I already requested.

This bug report is open, because there is no solution yet. And I don't
believe, that something will change.
