In my opinion most of these bugs are different.

It is possible that libparted does this when it uses sun disk labels
(but I don't know the internals of libparted). Partman doesn't have its
information on the disk. However there is the following bug in partman:
sometimes it considers the partition tables in its own data structures
unchanged and misses to write them to the disk. The result is that when
the type of some partition doesn't correspond to the file system in it
partman may miss to correct the partition type and latter grub fails.

Can you give more details about this?
