Read the whole comment for the integrify.py module:

+run this script on your repository to generate integrity data for
+rdiff-backup --verify-full
+
+WARNING this will not detect if your repository has already been corrupted.
+It will create integrity signatures with the files as they exist when you
+run the script. Any corruption that happened before that point can only
+be detected with --verify-at-time. However, after you run this script you
+can use --verify-full to verify that nothing has changed since you ran this
+script.

According to this, the script generates the integrity data, and
-verify-full simply uses this integrity data to confirm that nothing has
changed since the integrity data was generated.  I just don't see any
other way to interpret that.  You say you have a version with the patch
installed.  What happens if you run --verify-full before generating the
integrity data?
