Just to finish-up this thread:

The mythbuntu installer (14.04.01) completely failed to work on my machine 
(Core2Duo, onboard nvidia 9400, 8G ram).
It would install OK, but then crash or reboot, usually with screen 
corruption, within 30 minutes (usually ~10min).
These problems were exacerbated by high disk I/O load.

One particularly crappy aspect of this is that it looks for all the world 
like a hardware failure.

I re-installed Mythbuntu from the 12.04.04, and the box is running perfectly.

So for the time being (check date of this post) do not install Mythbuntu 
14.04 if you have an nVidia 4-digit-series video card (e.g.: 9400, 8600, etc.)
