Broken update

I tried to update my debian stable TDE-based system this morning, and received this error message: E: /tmp/apt-dpkg-install-96xDOO/031-tdebase-data-trinity_4%3a14.0.6~pre21-0debian9.0.0+7_all.deb: trying to overwrite '/opt/trinity/share/icons/crystalsvg/16x16/apps/kcmdf.png', which is also in package kdf-trinity 4:14.0.6~pre5-0debian9.0.0+0 Synaptic is reporting a broken package, but the instructions as to how to proceed in this situation are exceedingly unclear. Anyway. Something is obviously wrong, and it appears to be a TDE packaging error of some kind and I thought I should post here to put the issue before people who understand this a lot better than I do.
