They have orthangonal purposes, so unless you are asking if there are bugs in the block layer devices that support that combination, the question doesn't make a lot of sense. RAID 1 gives you protection against single drive failures. If you want that feature, then you are going to need it regardless of whether you are using LVM or not. LVM provides a way to manage how space is partitioned (and I think some other special features like snapshots) and if you need them, RAID 1 (or 5 or 6) isn't going to help you.
