After adding new language "Parent Section" field is empty

All actions should be performed in administrative console.

1. add new language
2. switch to newly created language
3. try to add new product
4. see, that "Parent Section" dropdown has only dashes in it, but no category names.

I propose, that we should show section name from primary language, when section translation in current language is missing (like we do with section tree on left frame).
