[TYPO3-news] [TYPO3-project-news] Unknown characters on TYPO3 tx_news list view (in Chrome)

[Adrian]

I noticed strange behaviour on TYPO3 tx_news list view. Sometimes on the bottom of the page appears unknown characters. I don't know how and why and it's only on one (list view) page and in chrome browser. Here is the sample of source code: 

<div class="footer-menu pull-right"><ul class="nav nav-tabs" role="tablist"><li class="first"><a href="http://bikeground.pl/" title="Strona główna">Strona główna</a></li><li><a href="o-nas/" title="O nas">"nav nav-tabs" role="tablist"><li class="first"><a href="http://bikeground.pl/" title="Strona główna">Strona główna</a></li><li><a href="o-nas/" title="O nas">"nav nav-tabs" ro" title="="Ok..=lip3Tole="twas">"na=>a-rss etrona g></av nav-tabs" ro" title="="Ok..=lip3Tole="twas">"na=>a-rss etrona g></av nav-tabs" ro" title==contijiav nav </div>

I have noticed that I can call out that behaviour when I change some tx_news configuration eg. "List actions shown in Flexforms".

Any suggestion what can be wrong?
