o I still saw problems in my brother's machine, XSL document could not be parsed, and   the (non intuitive for a newbie) solution is to select a stylesheet. o The KopetePrefs ctor have a fallback for that, but the setStyleSheet doesn't. If a dialog like   the current one does a setStyleSheet with a null string or a wrong one, it will break the chatview.
