broken `Launcher` after experimenting with `MyUnity` themes

Question

I used MyUnity to try some themes such as clearlooks and industrial and then I switched back to default. Now my Launcher is broken. How can I repair this?

There are many invisible items in the Launcher, such as shown here above the Google Chrome icon.

Edit: unity --reset results in thousands of error messages and warnings and the complete loss of the Launcher and top-of-screen task-strip. The execution of this command might take 15 minutes or more. unity --reset-icons also executes for at least 15 minutes, spews errors, and does not resolve the problem.

This is not a duplicate because the fix at that link does not work in this case. — H2ONaCl, Dec 07 '12 at 14:09

This procedure can fix it.

sudo apt-get install --reinstall humanity-icon-theme

sudo apt-get install --reinstall gnome-icon-theme-full

Then go to System Settings > Appearance > Theme and cycle between Ambience and Radiance, ending back at your preference. Shutdown and reboot.

Install this fix just in case it might prevent a re-occurrence of the problem.
