PHP5.3 warning: Parameter 1 to _tw_import_delimited_import_file() expected to be a reference, value given

While running PHP5.3, I noticed the above error message when trying to import a csv file into table wizard. Because of this the import fails. It looks like another one of those ref, value strictness bugs in PHP5.3.

Here's a rather simple change that seems to work on my box.

change in tw_import_delimited.module

function _tw_import_delimited_import_file(&$srcinfo, &$context) {
  if (!isset($context['sandbox']['total'])) {
    $context['sandbox']['total'] = filesize($srcinfo->filepath);
    $context['sandbox']['done'] = $srcinfo->offset;
    $context['sandbox']['rows'] = 0;
  }

to

function _tw_import_delimited_import_file($srcinfo, &$context) {
  if (!isset($context['sandbox']['total'])) {
    $context['sandbox']['total'] = filesize($srcinfo->filepath);
    $context['sandbox']['done'] = $srcinfo->offset;
    $context['sandbox']['rows'] = 0;
  }
