   If you're setting it to a string you've constructed, or will be
   appending to the column later, use "col_add_str()".

So it all depends on how you _start_ filling the column. If it's already
filled using col_set_str(pinfo->cinfo, COL_INFO, "Blah"); you'll need to
clear it first, like so:

    col_clear(pinfo->cinfo, COL_INFO);

Good luck,
