Bug Description

gnome-disk-utility "Disks", version 3.6.1-1ubuntu1

System in question:
   uname -a = 'Linux scorpio 3.8.0-19-generic #29-Ubuntu SMP Wed Apr 17 18:16:28 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux'
   lsb_release -a = 'Distributor ID: LinuxMint
                                 Description: Linux Mint 15 Olivia
                                 Release: 15
                                 Codename: olivia'
   (This is Linux Mint 15 MATE edition)
   lsblk = 'NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT

Attempted to format partition in question (/dev/sdc2, /dev/sdb2 before reboot) from ext4 to NTFS, failed to unmount partition beforehand. Admittably a failure in proper user policy; but a frontend graphical program like "Disks" should know better than to have actually tried to preform said operation without doing an unmount first. Result was a partition which read 16EB (exabyte) ext3/ext4 in caja shell properties window. Attempt to unmount via caja shell resulted in kernel panic :(

Clearly this is a very serious issue; anybody working on disk partioning could potentially make this mistake. Terminal format utilites would actually complain about mounted partitions-- the fact the "Disks" was able to format an in-use, mounted partition is very worrying.
