Description of problem:
nagious-plugins-file_age ceases to work with the update to 2.1.4-2.el6. Since this update, no matter which file I check, the plugin always returns "File not found".

Version-Release number of selected component (if applicable):
2.1.4-2.el6

How reproducible:
always

Steps to Reproduce:
1. Install nagios-plugins-all
2. run /usr/lib64/nagois/plugins/check_file_age somefile
3. result is "File not found"

Actual results:
/usr/lib64/nagios/plugins # ./check_file_age check_file_age 
FILE_AGE CRITICAL: File not found - "check_file_age"

Expected results:
./check_file_age check_file_age 
FILE_AGE OK: check_file_age is 1 seconds old and 3844 bytes  | age=1s;240;600 size=3844B;0;0;0

Additional info:
The issues seems to be the command in line 80:
>>
$opt_f = '"' . $opt_f . '"';
>>
This adds "" to the filename, which does not work. Commenting that line out fixes the issue.
