debian/patches/rootbackends-worldreadable.dpatch allowed backends to be installed as 0744 and still being run as root, which doesn't violate the Debian/Ubuntu policy as much as installing them as 0700. However, this apparently broke cups-deviced which seems to only recognize 0700 or 0755 backends.

As a workaround you should chmod ipp and http to 0700.
