Why is now suddenly dependency on koffice-trinity-dev for the kmplayer?

dpkg-buildpackage: info: source package kmplayer-trinity
dpkg-buildpackage: info: source version 4:14.1.0
dpkg-checkbuilddeps: error: Unmet build dependencies: koffice-trinity-dev

I feel I am getting old, but what does a kmplayer has to do with an office
app.

thanks
