From the Quicktabs queue:

quicktabs does not work in Panels with latest version of ctools
http://drupal.org/node/1910434

The fix to block.inc in comment #3 from that post does in fact fix the problem, but per the OP I'm not sure if this the right fix or if it needs to be fixed in Quicktabs. Here is the working fix for reference:

ctools/plugins/content_types/block/block.inc line 290:

if (!empty($block->content)) {
    $block->content = filter_xss_admin($block->content);
  }

to

if (!empty($block->content)) {
    $block->content = filter_xss_admin(drupal_render($block->content));
  }
