I can confirm this behaviour. This is introduced with WP3.3 and the newest version of Qtranslate. I went back to Wordpress 3.2 because of this problem. I even made a short video to document the bug. ...
A workaround seems to be that you never update the page in the visual tab, but the html tab. As described in this short flashvideo. Better solution would be a bugfix from Quian Qin though. I hope he reads this thread
@Tiles: Does this mean you have now WP 3.2.1 and qTranslate 2.5.28 working perfectly without this bug? I have to evaluate if this is necessary also for a site of I admin (I use WP 3.3.1 and qT 2.5.28). Hope also that we have a actual and working version of WP/qT shortly. This is a major problem!
And WP 3.3.2 and 3.4 RC3 is out.
