Parted Magic copy/paste doesn't work with Haiku (bfs)

Today, as I had to move a lot of partitions around for the upgrade to Karmic, I had the opportunity to check out the copy/paste partition capability on my small 1GB Haiku partition.
Unfortunately, although it gives the impression that it works, when you try to boot to the newly pasted partition, I got a "Partition not found" error.
This may well be because Parted Magic doesn't seem to recognize the bfs file system.
What was surprising, however, was that even the partition that I copied from was also rendered unbootable. I have no real explanation for this.
