I think I found a bug in v3.4 of GNU Parted.

This was my issue, put in removable media that had old Root and Home labelled partitions but they were mounted at /media/USER/xxxx.  I wanted to format and i got an error about overlapping partitions.

I used sfdisk to check my sectors start and end.

I outputted the partition table data to a text file and edited the overlap as I did find one on /dev/sdb. I used sfdisk -d /dev/sdb > ~/Desktop/sdb-backup.txt

After editing this text file to fix the overlap as my sdb1 end overlapped my sdb2 start, i re fed the new partition data back in with

sfdisk /dev/sdb < ~/Desktop/sdb-backup.txt

After being confident i fixed the overlap that was causing Parteds GUI to not open and the partitions were resized after feeding new adjusted data sectors to the disks with sfdisk,

I got this print out when using a command: parted /dev/sdb unit s print  to confirm the changes took place.  My terminal spit this out

You found a bug in GNU Parted! Here's what you have to do:

Don't panic! The bug has most likely not affected any of your data.
Help us to fix this bug by doing the following:

for further information.

Your report should contain the version of this release (3.4)

and the following history of commands you entered.
Also include any additional information about your setup you
consider important.

Assertion (metadata_length > 0) at ../../../libparted/labels/dos.c:2359 in function add_logical_part_metadata() failed.

Please advise on how I fix this bug or review v3.4 files and patch the bug for future versions.

Let me know if i was first to report this error in v3.4, not for reward but for personal pride and an ability to show off an email.

Thanks
