Running unity-greeter causes user settings to be altered and made unchangeable.

[Ankit Saini]

Steps to reproduce the bug:
- Start a new bash shell
- Run unity-greeter (You should have enough permissions as a user to run this command. Using `sudo unity-greeter` does not result in the bug)

The unity-greeter window now opens as normal but everything else becomes unusual. The user theme is switched to default gnome-2 theme and right clicking using two-finger touch does not work.
Trying to switch theme again does not work.

The only solution after that is to delete the ~/.config/dconf/user file and log in again. Of course, a lot of user settings are deleted due to it but everything becomes normal again.

Status changed to 'Confirmed' because the bug affects multiple users.

I can confirm this on Ubuntu 11.10 64-bit with unity-greeter 0.1.1-0ubuntu1.
After a user starts unity-greeter the current theme is changed.
I tried the gnome-tweak-tool to fix the theme but to no avail.
A solution is to restore ~/.config/dconf/user from a backup (you do back up your home directory regularly, don't you? :-) and log in again.
