Yep, exactly.  I would prefer someone to just fix it (since it IS something quite trivial) rather than revert.  This ends up being a massive change for the purposes of improving diagnostics here and downstream.

Typically it is considered somewhat fair to give the author time to fix a failure before reverting, and unfortunately this was discovered at 8pm on a Friday, so it seems longer than this would typically take.
