Basically I'm trying to resubmit the changes made in http://musicbrainz.org/edit/14487314 which failed on a dependency, and add in the six missing tracks. I add the tracks in (using the basic 'freetext' track editor), complete what's needed on the recordings and artists screens fine and everything looks good on the review 'edit note' screen. Then when I click Enter edit on that screen I get this:

"Internal Server Error

Oops, something went wrong!

Error message: (No details about this error are available)

We're terribly sorry for this problem. Please wait a few minutes and repeat your request — the problem may go away.

If the problem persists, please report a bug and include any error message that is shown above."

I've tried it on separate occasions, several hours apart, one attempt with a mix of linking existing recordings and adding new ones, and another creating new recordings for all six tracks. Both resulted in the same error screen, with no specific message given for the problem.
