keywords don't get imported

I was having trouble creating keywords as taxonomy terms. I think the problem lies in core.inc

$node->taxonomy['tags'][vocab id] is treated as an array when in fact it should be a string.

This worked for me. (Sorry it isn't a patch)

function taxonomy_import_html($profile, &$node, $datadoc = NULL) {
$node->taxonomy = (! empty($node->taxonomy) && is_array($node->taxonomy)) ? $node->taxonomy : array();

$active_vocabs = taxonomy_get_vocabularies($node->type);
if (!$active_vocabs) return;

$freetag_vocab = $profile['freetag_vocab'];

if ($freetag_vocab && !empty($node->keywords)) {
foreach ($node->keywords as $value) {
$node->taxonomy['tags'][$freetag_vocab] .= $value . ',' ;
import_html_debug(
"Found Keyword: $value",
$node->keywords,
WATCHDOG_NOTICE
);
}
}
