Mageia 6 crash on login, can't start desktop

Hi all, I'm having a trouble getting Trinity working on Mageia 6. I've installed via the official URPMI repositories, using the trinity-desktop package to ensure all dependencies are present. Note, I've got Trinity running OK on my laptop with Mageia 6, but on my desktop system it's badly broken for reasons I can't trace. My desktop uses an NFS mounted home directory and and is a dual-monitor system. If I use TDM as the login manager, the I get dropped out of X back to the terminal, TDM seems to be unable to start at all. I've switched to LightDM, which fixed this but TDE isn't listed as an available desktop in the relevant menu. Fixing this required a symbolic link from /opt/trinity/share/apps/tdm/sessions/tde.desktop to /usr/share/xsessions. If I login the initial splash screen appears, but I then get a crash message which closes before I can read the details, I then get dumped back at the login manager. If I login using XFCE and try to run starttde, then I get same behaviour and again, the crash handler vanishes before I can get at anything useful. I see the following at the command prompt: [starttde] Starting starttde. [starttde] This script is /opt/trinity/bin/starttde [starttde] TDE version is R14.0.4 [starttde] TDE base directory is /opt/trinity [starttde] TDEHOME is not set.

Note, I'm not sure why this is complaining about /home/timw/.DCOPserver_baa.sheep__0, I've checked prior to start up and this dir does not exist, nor is it left behind after the crash. I've tried using a clean user account and also running this as root, but there is no difference, the start up just crashes. I've audited my system and have removed all the left behind Mageia 5 packages, so the installation is clean as far as I can tell. TDE programmes such as konqueror, kate etc start up OK running on XFCE. Any help much appreciated, I'm somewhat lost without my Trinity desktop and this is my primary work computer.
