This issue can also occur when you programmatically create taxonomy terms and then translate them programmatically too, because the content_translation_uid field is NULL in the database by default. When you go to re-save the previously created translation in the UI you get the above error message because it defaults to the anonymous user (0) when assigning a value via the form.
Patch from #128 works for me and the content_translation_uid is still correctly assigned.
