Your report provides a clue that the problem may be specifically with the admin (though the ticket doesn't mention admin), where (without actually looking at any code) I could guess the path taken to save the new model with an uploaded image somehow bypasses however these fields are normally set. You might want to note in that ticket how you are encountering this problem in the admin. The ticket also notes a custom save method can be used to get around the problem, which you may want to try if you want to get things working before the root cause of the problem is identified and fixed.
