Currently, if you want to translate a page that contains a ListBlock with a StructBlock, and that StructBlock itself contains an ImageChooserBlock (or a DocumentChooserBlock), and you select something in the original page, the edit-page of the translated page will always fail with the following error:

TypeError: 'NoneType' object is not subscriptable
The used StreamBlock for the StreamField looks like this:
from wagtail import blocks
from wagtail.images.blocks import ImageChooserBlock
class PageStreamBlock(blocks.StreamBlock):
team = blocks.ListBlock(blocks.StructBlock([
('image', ImageChooserBlock(required=False)),
('name', blocks.CharBlock()),
]))
Only setting a "name" in the above example, won't result in a crash, but as soon as you select an image, it will fail.
