Error: Unable to satisfy all constraints on the partition.

[Thomas Schweikle]

Hi!

I have found the following bug with parted/gparted:
Error: Unable to satisfy all constraints on the partition.

even with commands only accessing the unit reading only:
parted /dev/sda unit s print

The device is partitioned. fdisk prints:
address@hidden /root % fdisk -l

Disk /dev/sda: 250.1 GB, 250059350016 bytes

cfdisk refuses to start:
FATAL ERROR: Bad logical partition 6: enlarged logical partitions
overlap   Press any key to exit cfdisk

Other tools (Windows-based, acronis disk-director) do not see any
problem with partitions on this disk.

It may be a bug, as far as I am concerned.
