I had to go back a couple of weeks ago to version 0.92 as I couldn't get the DVD burner to work properly. There was also a problem with XSANE wanting permission to run as root. Uninstalling and reinstalling the packages didn't work and I needed to scan and burn and it was a real pain. Fortunately going back only took about 2 hours which includes the time for reinstalling all of the patches and restoring my settings from backup that I had made earlier.
The machine is running smoothly and when 0.94 comes out (or a major patch to 0.93) I will be doing another upgrade (after backups of course).
