I got the following error on Google Chrome 17.0.963.83:
----
Uncaught TypeError: Cannot read property 'content' of undefined

window.liquidThreads.doReloadThread load.php:18
jQuery.Callbacks.fire load.php:14
jQuery.Callbacks.self.fireWith load.php:15
done load.php:112
jQuery.ajaxTransport.send.callback

When the error happened the following line of code was selected in the [Script] tab:

'<div class="mw-ajax-loader"/>');var header=$j('#lqt-header-'+threadId);thread.prepend(loader);var apiReq={'action':'query','list':'threads','thid':threadId,'format':'json','thrender':1};$j.get(mw.util.wikiScript('api'),apiReq,function(data){var html=data.query.threads[threadId].content;var newContent=$j(html);thread.empty();thread.hide();header.empty();header.hide();var newThread=newContent.filter('div.lqt_thread');var newThreadContent=newThread.contents();thread.append(newThreadContent);thread.attr('class',newThread.attr('class'));thread.find('.lqt-post-wrapper').each(function(){liquidThreads.setupThread($j(this));});header.fadeIn();thread.fadeIn();var targetOffset=$j(thread).offset().top;$j('html,body').animate({scrollTop:targetOffset},'slow');},'json');},'setupThread':function(threadContainer){var prefixLength="lqt_thread_id_".length;$parentWrapper=$j(threadContainer).closest('.lqt-thread-wrapper').parent().closest('.lqt-thread-wrapper');if($parentWrapper.next('.lqt-thread-wrapper'
