gparted will fail mid-operation because of XFCE automounting the drive. This could be a serious problem resulting in filesystem corruption and data loss, depending on whether or not the interrupted operation is recoverable. See Launchpad bug

"On startup, gparted ends up causing remove/add events to happen for
unmounted partitions. Udisks has some logic in it to NOT auto mount
partitions that show up on a disk that itself wasn't just hot plugged to
prevent this sort of thing from happening. I guess xubuntu uses
something else for auto mounting that isn't quite so smart?"

"This is still a problem in Xubuntu 14.04.1. It can cause gparted to
fail mid-operation, e.g. the operation partition resize (which takes the
existing filesystem and moves it left and then grows it) will fail
immediately after the move left. This leaves the disk in a state where
the partition has been expanded, but the filesystem it contains has not,
so the filesystem does not fill the partition and needs to be repaired."

Title:
  Xubuntu install fail due partition auto mount defeats Gparted

Status in Thunar file manager:
  Confirmed
Status in “gparted” package in Ubuntu:
  New
Status in “thunar” package in Ubuntu:
  Confirmed

Bug description:
  Wanted to install Xbuntu 12.10 along side Win 7 and Ubuntu 12.10.
  Needed to create 4 further partitions (boot,swap,/ and home) in a pre-
  exsisting extended partition. Booted from a Xubuntu 12.10 Live CD on
  my HP Envy Sleekbook and ran up Gparted.

  What I expected to happen:
  I expected to be able to shrink a 230gig partition and create 4 additional partitions. To my surprise the extended partition was already mounted when I selected unmount partition in Gparted, Gparted completed the action but then Xubuntu remounted it automatically and opened a filemanager window for every other partition as well.

  What happened instead:
   I found I could not unmount any partition without it being automatically remounted.

  Installed Xbuntu 12.10 on my Desktop (clean install from a CD). Using
  Gparted I cannot unmount a spare partition without Xubuntu
  automatically remounting it.

  The Automount feature needs an operator control to allow use of
  Gparted.
