Media Type property causing exception on legacy media items
I've added an Alt Text property to the Image media type in a 4.7.1 installation, however legacy media items (i.e. images that were in the media library before I added the property) now can't be loaded in the medi tree as it throws the following exception:
Value cannot be null.
Parameter name: Property altText (689) on Content Type Image could not be retrieved for Document 1085 on Tab Page Image. To fix this problem, delete the property and recreate it.
I don't want to remove the property as this will erase all of the data for the alt text that our client has added to the new media items.

Is it specified as cannot be null and, if so, does the problem go away if you allow it to be null?
