Backport #1763 to 2-3-stable?

In the project where I work, using Rails 2.3.4, we just found out
we're affected by the bug described on lighthouse ticket #1763. It's
marked as resolved, but the relevant commit is only on master (
98eaa2c6834e418959f2a1a18421e4811167e03b ), not on 2-3-stable. Would
it be possible to "backport" it to 2-3-stable? From what I saw, it
would only take a cherry-pick from one branch to the other.
