For anyone encountering this bug, a workaround to allow the removal of the broken package is to first stop your X display manager, then use remove the packages manually on the command line, and finally reboot. This will switch you back to Nouveau but at least give you a working system from which you can reinstall the older NVIDIA package that is not afflicted by the bug.
