This is one of the few occasions when you really want to use dd itself.
Take an image of the disk and play around with that. If it all goes to hell, copy it again and try something else. I'm surprised the GUI tool would mess up, but I wouldn't use it myself.
Then again, I'm anal about backups - especially
when screwing around with partitions that contain data I care about.
