# 4) Open the change in Gerrit UI, select diff from Patch set 1 -> Patch set 2.
# 5) Notice both the old and new file name are listed (rather than only a rename, due to the comment).
# 6) Expand 'somerandomfile' (still on diff Patch set 1 -> Patch set 2).
# Observe server error and HTTP/500 response.
