TYPO3 Core

1. goto your own workspace
2. enter new content and make a translation afterwards (using the dropdown language Selection in edit mode, perhaps you are in 'de', switch to 'en [new]'
3. "Error 1": "Reference" shows "invalid value ({content id})"
4. save translation and publish content
5. stay in your workspace
6. edit and save the new content in source language again
7. "Error 2:" Language selection in edit mode of the source translation shows up again "en [new ]"

-> clicking "new" and saving content results in an doubled translated content Elementfor the translated Language

-> the already translated ContentElement shows a correct reference to his parent and the diff of the changed content

-> saving a "second translation" results in troubles of wrong references and so on...

reproducable on 4.00 to 4.1.2
