Description:
------------
There are some jpegs that are detected as Linux/i386 core file. This is only fixed in libmagic 5.18,
currently php uses 5.17. See https://github.com/file/file/commit/7e21b5477712cedf70403624d705c6cd7656a780for
the change in libmagic. 

There is currently no way to work around this as the magic file is compiled into php
