[Message part 1 (text/plain, inline)]

Is this a bug, or am I doing something wrong? I didn't know it was
possible to make gpt partitions 0 sectors wide.

What created this partition table? It looks like partition 3 is wrong,
it covers 105GB to 1000GB but both partition 2 and partition 5 also use
some of that space. This is likely confusing parted, so I'd say it isn't
a bug, it's just trying to do the best it can with the available space.
