Comment 34 for bug 574822

If both UNE and GNOME use the same configuration files and this causes UNE not to malfunction, they either they should look for the configuration files in different places, or they are conflicting.

To say the that user can have both in the current state is to leave it to the poor newbie the task of figuring out that having both will cause problems. In most cases the newbie will not sort that out and perhaps will think it's better to go back to Karmic, Jaunty, or Windows.
