In a multilingual installation (5 languages in my case), if you
1) edit an object in a secondary language,
2) then click the VIEW button (view the draft that is being edited)
3) then click the PUBLISH button
you can view:

• a new object with no name
• the object, that you have just edited, has only the translation you have edited: other translations are removed.
  Both objects are not editable, removeable, etc., as well.

  Steps to reproduce

  Multilingual installation of eZPublish 3.8.6
  1) Create an object (a folder) in the principal language (English)
  2) Add a translation of this folder in another language (for example, in Italian language)
  3) Edit the Italian translation
  4) Click the View button
  5) Click the Publish button
  Now you can view the critical problem above descripted.
