Package: python3-django-allauth
Version: 0.51.0-1
Severity: normal

Dear Maintainers,

Yesterday we discovered that reaching the rate limit of the registration page of our Mailman installation throws this exception (and a lot of emails, sigh!):

ERROR 2025-05-13 01:34:04,725 1324 django.request Internal Server Error: /mailman3/accounts/signup/

raise TemplateDoesNotExist(template_name, chain=chain) django.template.exceptions.TemplateDoesNotExist: 429.html

To generate this page, mailman3 use allauth package; when rate limit is triggered it
tries to display a page for error 429 but cannot find the corresponding template.

My impression is that

* a missing template should not throw such a serious exception
* the task of providing the template is of this package, as it is hardcoded in ratelimit.py

but I could be wrong.

Best regards.

Paolo
