The recent version of GNU Datamash ( http://gnu.org/s/datamash ) has a new 
operation 'check' to quickly diagnose cases like this (non-tabular file 
structure) and provide verbose report of the problem.

Example:

    $ curl -s https://ptpb.pw/c1Vu > test.txt
    $ datamash -W check < test.txt
    line 89 (2 fields):
     cower cower
    line 90 (3 fields):
     deluge-labelplus deluge gtk2
    datamash: check failed: line 90 has 3 fields (previous line had 2)


The '-W' parameter tells datamash to use whitespace as field-separator (default 
is tab).
