Even if ACL support is included in the kernel, it is not necessarily enabled by default when mounting.
You need to add the mount option in /etc/fstab or use "tune2fs -o acl" on the partition to have ACL support enabled by default.

I don't know if the Ubuntu installers always added 'acl' as a default mount option for the root partition, but even if it did, there is always the fact that people can have used other programs (e.g. GParted, or another linux system) to partition their hard disk(s), so there is no guarantee that ACLs are enabled on every filesystem by default.

IMO udisks should not fail on filesystems that don't have ACLs enabled (it works just fine without ACLs, except for this bug where it sets the ACL without properly checking support for it).
