Crashes when using gnome tweak tool with Gnome 3.4

Well i'm new in this site and i have some problems with Ubuntu 12.04

I made a clean installation and install gnome 3.4, gnome classic and cinnamon but when i want to run gnome tweak tool in gnome 3.4, it closes immediately, in Unity, Cinnamon and gnome classic it runs perfectly.

Also I always receive a warning about Ubuntu crashed and sometimes it reboots Can you help me in this?

Solution 1:

If you try running it from an terminal and you get this error:

(gnome-tweak-tool:4506): GLib-GIO-ERROR **: Settings schema 'org.gnome.shell.extensions.user-theme' is not installed
Trace/breakpoint trap (core dumped)

Then you can run the following two commands from a terminal to add the schema to the system:

sudo cp $HOME/.local/share/gnome-shell/extensions/[email protected]/schemas/org.gnome.shell.extensions.user-theme.gschema.xml /usr/share/glib-2.0/schemas
sudo glib-compile-schemas /usr/share/glib-2.0/schemas

To run gnome-tweak-tool from the command line start Terminal and just type:

gnome-tweak-tool

And press enter
