undefined method to_url for nil:NilClass when creating taxonomy

[mbajur]

My spree instance is throwing undefined method 'to_url' for nil:NilClass

Context

It's happening when I'm trying to create a taxonomy either using admin panel or directly via console. Name of the taxonomy is being provided as expected.

Actual Behavior

Steps to Reproduce

1. Create a store
2. Set it's default locale to PL
3. Set supported locales to EN and DE
4. Try to create a new taxonomy

Your Environment

Hello
also have the same issue with two different install. One starter and one that do myself.
Anybody have a solution?

I did some investigation on this one - it seems that when store.default_locale is different from I18n.default_locale, Mobility's fallbacks return a nil for the name (instead of the name that was set when creating the taxonomy).

I'll dig a bit deeper into it, as this seems to be an edge case for translation fallbacks in general. I think creating a Taxonomy is the only place where it really surfaces, but it would be great for the fallbacks to work consistently across the board.

@mbajur I've just pushed a fix with Spree 4.6.1. Please take a look and let me know if that works fine for you now.

I can confirm it indeed fixed it. Thank you! 🙌
