Created attachment 2531 screenshot - bug of xfce 4.6.1 shutdown screen there's a little bug in the logout screen of (the german translation, maybe other languages, too?) A little snipped of (I guess) xml-code has crept in: "<span size='large'><b>[username] abmelden</b></span>" it should be that way: "[username] abmelden" instead of the xml code tags arround it. I have put screenshot is in the attachment. Don't know, if other traslations are affected, too.
Should actually be fixed for a long time now in SVN/Git repositories. It's due to the middle dot between span and size; the XML stuff is perfectly fine as it is interpreted by Pango. Some people in the web provide revisioned and compiled translation files for that, or you might want to grab latest Git and compile on your own or fix the translation from 4.6.1 on your own... (And somehow I think that there is already a bug report for that issue)
