OK, so...

a) You say Buster. Where did you install TDE from? What version? As far as I 
know, for Buster you need the premilinary builds.

b) You say KDE 3.5.10. I seem to remember that install instructions said to 
purge any KDE 3.5 elements befor install. So yes, KDE 3.5 and TDE clash. It's 
known. I guess that's because thes share files with the same name, but 
different contents.

If you want Trinity, you should better install on a system with no KDE, and 
running a testing TDE on a testing Debian, I'm not really surprised you 
encounter some problems.

These are caused by your environment, not by Trinity itself.
