Circular reference exception when deleting page with referenced image in 'For This Page'

3. Drag and drop image to the Content area.
4. Move page to trash. A confirmation dialog appears "Would you like to move the page page-1 to the trash?"
5. Click Move to Trash.

Expected: Move to trash successfully without warning message.

WORKAROUND: Define language settings on the root page.
