udev fails to mount repartitioned FAT32 USB pen drive until unplugged, replugged in

[nUboon2Age]

Binary package hint: udev

To reproduce this bug I take a USB pen drive (two I used were both 4GB but different manufacturers).
1. Using GParted,
  a. make new partion table
  b. make one partition FAT32, label no more than 13 characters long.
2. observe drive is not visible on desktop anymore.
3. Close GParted
4. Observe drive is not visible on desktop
5. Open GParted and see that drive is not seen.
6. Only remedy found so far is to unplug and replug in USB pen drive.

1) The release of Ubuntu you are using Ubuntu release: $ lsb_release -rd
Description: Ubuntu 10.04 LTS
Release: 10.04

2) The version of a) udev: $ apt-cache policy udev
udev:
  Installed: 151-12
  Candidate: 151-12
  Version table:
 *** 151-12 0
        500 http://us.archive.ubuntu.com/ubuntu/ lucid/main Packages
        100 /var/lib/dpkg/status

b) parted $ apt-cache policy parted
parted:
  Installed: 2.2-5ubuntu5
  Candidate: 2.2-5ubuntu5
  Version table:
 *** 2.2-5ubuntu5 0
        500 http://us.archive.ubuntu.com/ubuntu/ lucid/main Packages
        100 /var/lib/dpkg/status

3) What you expected to happen: after partition, drive auto remounts
4) What happened instead: after partition, drive not mounted until unplug and replugin
