Description:
When using libreoffice as a non-interactive command line tool, the exit status seems to always be zero even if fatal errors occurred.   This causes unsuspecting scripts to continue their merry way without realizing that something went horribly wrong.

The Linux/Unix rule is that a ZERO exit status means "success" and non-zero means otherwise. 

Steps to Reproduce:
1. libreoffice --convert-to "bogus" /dev/null
>Error: source file could not be loaded
2. echo $? 

Actual Results:
0 exit status

Expected Results:
non-zero exit status


Reproducible: Always

Additional Info:
For reference, here is a complete command to extract sheets from a spreadsheet into .csv files in the current directory.  You can substitute valid and invalid input file names
to test "working" and "failing" cases:

libreoffice --convert-to "csv:Text - txt - csv (StarCalc):44,34,76,1,,,true,,true,false,-1" FILE.xlsx
