p.a.registry import broken

hi,

when exporting registry via GS and reimporting the result, following error occurs

Traceback (innermost last):
  Module ZPublisher.Publish, line 138, in publish
  Module ZPublisher.mapply, line 77, in mapply

exported XML looks like:

<record name="bda.plone.shop.interfaces.INotificationTextSettings.order_text" interface="bda.plone.shop.interfaces.INotificationTextSettings" field="order_text">
    <field type="plone.registry.field.List">
      <title>label_order_notification_text</title>
    </field>
    <value>
      <element>{'lang': 'de', 'text': u'lkj\xf6\xe4'}</element>
    </value>
</record>

Form schema is defined here - https://github.com/bluedynamics/bda.plone.shop/blob/master/src/bda/plone/shop/interfaces.py#L282

@rnixx I believe you need to add <value_type type="XXX"/> within the <field> tag. However, I don't know what XXX should be...
