--- Comment #6 from Zebediah Figura z.figura12@gmail.com --- Apologies, that's not what I meant; I should have been more clear.
I meant to bisect Staging against current master—i.e. to apply all patches with `patchinstall.sh --all --backend=git-am --force-autoconf`, and then to bisect that against master. That should (hopefully) determine which patch in Staging causes the problem.
