I'm afraid I spoke too soon. In general use on the desktop it has been fine (I even had compiz running). However, I had left euphoria screensaver running overnight and I've come back to it twice now humg; this time I ssh'd in and found it was a hung X server; killing the X server got me control back. I've included two Xorg.0.log files; the 'hung' one is the one where it was hung - last thing is a power management command. (To make it clear, it has managed power saving and running this screensaver - so it's not an everytime). In this hung state the X server wouldn't let me attach with a gdb or allow me to strace it to see what it was up to.
I've also included the log from me trying to restart it - it complains of EngineRestore 'Idle timed out'.
