If I try to download the raw diff, I receive this error message: Unhandled Exception ("Exception") No configured storage engine can store this file. See "Configuring File Storage" in the documentation for information on configuring storage engines.
Ah, sorry: The diff of https://reviews.freebsd.org/D14003
This should be fixed by turning the frontend proxy or the backend server, note that the "D14003.diff" is 8.4 MB.
