Yes, thanks for catching this! You can fix it by changing function qa_db_user_recent_qs_selectspec(...) in qa-db-selects.php as follows:
$selectspec=qa_db_posts_basic_selectspec($voteuserid, false, false);
... to ...
$selectspec=qa_db_posts_basic_selectspec($voteuserid, false);
I'll fix this also for the next release.
