(was: Beta Release Editor: seeding Beta with a just-created Release Group from Stable causes crash)
Only tried to seed beta one time. After the error trace / failure to enter edit, I removed the release group from the editor and the edit then went through. Not sure if this is reproduceable all the time.
http://beta.musicbrainz.org/release-group/9b182592-6093-4697-9b2f-528d2db48850 existed at the time of the attempt to Enter Edit.
The seed: [removed]
The error trace on Edit Note page: [removed; essentially said that release.release_group refers to a nonexistent RG]
