Greg, that solved the issue :-)

The solution looks like this: In .xinitrc (or whatever you use to start your DE), I put these lines:

	export TDE_FULL_SESSION=false
	export TDEHOME=$HOME/.trinity
	export TDEROOTHOME=/root/.trinity
	export TDE_SESSION_UID=$UID
	export TDE_MULTIHEAD=false
	export TDEDIR=/opt/trinity
	export XDG_CONFIG_DIRS=/opt/trinity/etc/xdg
	export XDG_DATA_DIRS=/opt/trinity/share:/usr/local/share:/usr/share
	tdeinit_shutdown
	tdeinit
	# start whatever WM you need
	fvwm

Now "kcontrol" comes up with all modules, clicking on *.pdf in "kmail" brings up kpdf, "konqueror" works as expected :-)
