bug#23059: parted Debian 8

[Ｖ字龍]

(This is a re-send attempt as I seems to be failed to send to the mailing list itself)

Hi, I have the similar symptom myself so I'd like to share some of my details.

I recently bought an Intel SSDSC2BW240H6 240GB SSD and (probably) formatted to a msdos partition table using GNOME Disks(which seems to be Parted-based) then partitioned to "install" Ubuntu 16.04(and by "install" I mean I formatted an EXT4 filesystem and rsync'd the entire rootfs of my previously using Ubuntu 16.04 to the new filesystem then re-install the bootloader) via an USB 3.0 USB-to-SATA interface on a laptop.  The "install"ation went normally.

Then after few days later, recently, I plugged the new SSD on my desktop and working on a project which internally calls `parted` command for some information I encountered this "bug".

You found a bug in GNU Parted!(...)

Assertion (metadata_length > 0) at ../../../libparted/labels/dos.c:2313 in function
add_logical_part_metadata() failed.
```````````````

I can still reproduce on current master branch.

I'm a 100% Ubuntu/GNU/Linux user and I alway use Parted-based application to do disk partitioning so I'm pretty sure it's not some proprietary applications' issue.  Here's the fdisk output:
