Comment (by achbed):

 The only reason I added that is to catch situations where a sideloaded
 file is in a folder that can be read, but is not readable itself due to a
 permissions issue.  `is_file` just validates that the file exists and is a
 "normal" file, not that it's also readable.  We could add a separate
 ticket for that, but I figured that this would be an applicable spot to
 add that check.
