Can't launch Gnome Tweak Tool when the User Themes extensions is enabled.

When I tried from terminal, the output was:

petr@sova:~$ gnome-tweak-tool 

(gnome-tweak-tool:6475): GLib-GIO-ERROR **: Settings schema '' is not installed

Trace/breakpoint trap (core dumped)

Gnome Tweak Tool works correctly without User Themes.

Ubuntu 12.04, gnome-shell 3.4.1

Relevant (closed) question: Gnome-tweak-tool doesn't start

Add the official Gnome Shell Extensions ppa:

sudo add-apt-repository ppa:webupd8team/gnome3
sudo apt-get update

Install dependencies:

sudo apt-get install gnome-shell-extensions
sudo apt-get install gnome-shell-extensions-common

Afterwards, enabling on the link provided works fine.
