In addition to already posted .xsession solution you can:
a) Delete content of /opt/trinity/share/apps/tdedisplay/app-defaults (this
is probably what you did last time if update caused this to reappear)
b) Deselect "Apply colors to non-tde applications". But this have much wider
implications and generally undesirable "solution".

This bug was reported years ago. Also its not python that fails, its
specifically tkinter - almost all other apps reacts to bullshit in
xresources adequately (throw warning and use some sane defaults)
