TYPO3 Core

I try to edit the metadata of a translated tt_content element. When clicking on the edit button of the image inline element i get a fatal error with the message:

#1437656456: $uid must be positive integer, 0 given

This happens when there is no file metadata translation created previously.

While i know why this happens a regular editor will not understand it that easily. The expected behaviour is:

a either create a translation of the file metadata on clicking the edit button
b or do not show the edit button at all but render a + button to add the translation

Having neither of these solutions leads to bad ux
