I'm unable to run Ubuntu Tweak. It seems to have a problem with Python or something, but I'm not sure.

Here is the output:

/usr/lib/python2.7/dist-packages/gi/overrides/ RuntimeWarning: You have imported the Gtk 2.0 module.  Because Gtk 2.0 was not designed for use with introspection some of the interfaces and API will fail.  As such this is not supported by the pygobject development team and we encourage you to port your app to Gtk 3 or greater. PyGTK is the recomended python module to use with Gtk 2.0
  warnings.warn(warn_msg, RuntimeWarning)

Which version of Ubuntu are you using? I don't think Ubuntu Tweak has been updated to work with Ubuntu 11.10 yet, if that is your case. – Christopher Kyle Horton Oct 20 '11 at 15:42
@WarriorIng64: 0.6, and yes, it's supposed to be updated for 11.10 in the PPA. – RolandiXor Oct 20 '11 at 15:44

A recent update seems to have fixed the problem.
