Disabling fsckobjects in fetchgit?

Is it possible to get fetchgit to clone a repo that has a fsck error ?

Specifically, I’m using bundlerEnv to try & install rails 7-0-stable from github.com/rails/rails, which produces error: object 4cf94979c9f4d6683c9338d694d5eb3106a4e734: badTimezone: invalid author/committer line - bad time zone
