Unable to load profile picture with custom role

I’ve created a custom role with the Members plugin and added “upload_file” authorization to this role.

If a user with this role try to change his profile picture, he can access to the media uploader but when he try to upload his picture he get an error indicating he has no right to attach files to this content. The only way he can change his profile picture is to go to the media library, upload his picture, go back to his profile page and select this picture.

Is there another authorization to add to this role or is it a small bug in the plugin?
