Error in updating manufacturers images

I choose Manufacturer.
From list select one manufacturer
remove the picture for it.
Upload new picture
Save it.
It throws internal error.

Still after that everything works fine. Probably an exception but not sure why?

I have almost the same problem.

I added a product and associated it to a manufacturer. So when I press on the manufacturer i get an error:
{"Sequence contains no elements"}
The code error is:
System.InvalidOperationException was unhandled by user code
