parted -m option, don't show type field

[lisaac]

Hi,
Im using parted to show the disk partitions, It works well:

parted /dev/sda print free

Model: ATA VBOX HARDDISK (scsi)
Disk /dev/sda: 8590MB
Sector size (logical/physical): 512B/512B
Partition Table: msdos
Disk Flags:

Number  Start   End     Size    Type      File system     Flags
        32.3kB  1049kB  1016kB            Free Space
 1      1049kB  7516MB  7515MB  primary   ext4            boot
        7516MB  7517MB  1048kB            Free Space
 2      7517MB  8589MB  1072MB  extended
 5      7517MB  8589MB  1072MB  logical   linux-swap(v1)
        8589MB  8590MB  1049kB            Free Space

but I'm using "-m" option, the type field is blank:

parted -m /dev/sda print free
