bug#25718: 25718

ADDITIONAL info.

further investigation on Ubuntu 16.04 repositories:

- found 'partitionmanager' 1.2.1-0ubunrtu1 file,disk and partition 
management for KDE package

Partition Manager is a utility program to help you manage the disk devices,
partitions and file systems on your computer. It allows you to easily 
create,
copy, move, delete, resize without losing data, backup and restore 
partitions.

Partition Manager supports a large number of file systems, including 
ext2/3/4,
reiserfs, NTFS, FAT16/32, jfs, xfs and more. Note that to gain support for a
specific file system other than ext2/3/4, you should install the 
corresponding
suggested package.

Partition Manager is based on libparted (like gparted) and makes use of the
KDE libraries for its user interface.

- it was installed; the interface is similar to 'gparted'

- it solved the problem successfully; it even recovered the partition 
and its contents.
