Thanks Samuel for spelling it out. Handing someone bunch of stuff as if to say "here, you figure it out" as was done earlier never gets anything done very quickly or well.
After some deep Googling, I found a Dutch site that addressed the Inove issue by adding 6 characters to the footer.php code.
I will still stay at 3.4.2 due to other reported major issues with 3.5, however, and there are no real security issues presented by not upgrading at this stage.
In the event others are seeking this out for Inove, here is the fix. Chrome will translate the page in question, but use the non-translated page for the code:

Find the line:
$post_datetimes = $wpdb->get_row($wpdb->prepare(“SELECT YEAR(min(post_date_gmt)) AS firstyear, YEAR(max(post_date_gmt)) AS lastyear FROM $wpdb->posts WHERE post_date_gmt > 1970″));
Replace with:
$post_datetimes = $wpdb->get_row($wpdb->prepare(“SELECT YEAR(min(post_date_gmt)) AS firstyear, YEAR(max(post_date_gmt)) AS lastyear FROM $wpdb->posts WHERE post_date_gmt > 1970″, null));
Actually, pasting in , null after 1970″ is all that is needed.
