Description of problem:
Running "file -i" does not always return a valid MIME type. In my case I tested 
a pdf file and expected a return value of "application/pdf", but got "PDF 
document". When asking 'file' for MIME output the default magic file 
is "/usr/share/magic.mime". Investigating this file shows that one would get 
non-MIME strings in many other cases.

Version-Release number of selected component (if applicable): file-3.35-2


How reproducible:
Always

Steps to Reproduce:
1. execute 'file -i my_pdf_file.pdf'
	

Actual Results:  file: Using regular magic file `/usr/share/magic.mime'
my_pdf_file.pdf: PDF document


Expected Results:  file: Using regular magic file `/usr/share/magic.mime'
my_pdf_file.pdf: application/pdf
