I've been getting this all day when trying to browse my recent edits, as soon as I click on page 2 (pages 1 and 3 display without issue). Thinking it might be a problem with a specific edit, I tried looking at the edit history for a particular artist that performed on a release I edited recently, and got the same error: https://musicbrainz.org/artist/88ec8580-cbdf-4a06-9cf1-2f501391b279/edits.

The complete dump is:

Internal Server Error

Oops, something went wrong!
