I agree.  Very strange indeed.

To quickly see if the problem existed in the old parted-1.8.8, I booted 
up GParted Live 0.4.6-1.  After performing the same series of steps with 
gparted I did not experience the problem of parted failing to recognize 
the file system.

Based on this we can't simply conclude that the problem was introduced 
by code changes to parted.  Besides the code changes between parted 
versions 1.8.8 and 2.2 (with the BLKPG patch), many other things have 
changed too, such as the GNU/Linux kernel and udev.

Ideally to isolate the problem down to parted only, I need to compile 
parted 1.8.8 for use with the ubuntu-10.04-beta2-desktop-i386.iso 
image.  I will try installing Ubuntu 10.04-beta2 and then compiling 
parted-1.8.8 to re-test the parted file system recognition problem.
