MCVE of the failing part:

def f():
    def f():
        message = ngettext(
            "%s rappel a bien été envoyé.", "%s rappels ont bien été envoyés", len(validations)
        ) % (len(validations))

Works with #1958, so likely a duplicate of #1629

Hello!

All reproduction cases in this issue format without error on master. The fixing commit was 8672af3 from PR GH-2126. I'll be marking this issue as a duplicate of GH-1629 since that's what GH-2126 aimed to fix and it's highly likely this issue falls under GH-1629.

Since we use the issue tracker as a reflection of what's on master, I'll be closing this issue. If you have any issues, especially with the new (but stable) output, please open a new issue. Oh and the fix should be available in a published release soon, see GH-2125 for more info.

Thank you for reporting!
