 Hello,
 I'm also having problems after 4.7.1 update with uploading non image
 files.
 It seems to break at the part where validation tries to get "real_mime"
 using "finfo_file"
 As i see "real_mime" is undefined when it's compared to $type

 Googled that "finfo_file" is only on PHP >= 5.3.0, and I'm running on
 5.2.17.
 Maybe that's the peroblem? I think that "function_exists( 'finfo_file' )"
 should then return false, but it returns true. But I'm not a PHP developer
 so thats not the staff I really understand.
