Sorry, GNOME shell failing to start was due to the schema being out-of sync with the extension. Should be fixed in trunk. You can repair this locally with
$ sudo glib-compile-schemas /<email address hidden>/schemas/
or wait for a new snapshot.
In my tests I could then disable auto-show in preferences and it didn't get re-enabled.
