29623	DurationField's overflow error message fails to translate	Jannis Leidel	Markus Holtermann	"In https://github.com/django/django/commit/55b5393bd235aa6c55ea9a7da6f0e8b75b204084 a new ValidationError message was added that isn't using the common pattern of using string substitution variables but instead a format string.

I noticed this while updating the German translation for 2.1 and found Transifex to not display the variables correctly which could prevent translators to correctly set the variables in the translated string.

In my experience translators can mistake ""{variables}"" in text as something to translate as well, which effectively can lead to either KeyError (because the expected format variable weren't found) or empty fill-ins.

Either way, this is a possible breaking change."	Bug	closed	Forms	2.1	Release blocker	fixed			Accepted	1	0	0	0	1	0
