Comment # 1 on bug 1227145 from Brandon Bigam

I came here to report this and see it already here. 

Specifically, package libreoffice-24.2.4.2-3.1 unconditionally recommends
libreoffice-qt6. This package depends on various KDE libraries, and, through
the chain of recommends, brings in quite a lot of KDE, which isn't needed or
helpful outside of an (intentional) KDE Plasma setup. In my case, it's in Xfce,
and I'm glad I noticed before all those KDE packages were pulled in.

This would affect a great many people as they update libreoffice with
recommends from DEs other than Plasma, so I suggest changing the dependencies
quickly. However it worked with libreoffice-qt5 seemed to be fine.
