I confirm this bug both on amd64 and i686. It is not related to the particular session as choosing twm, for example, rather then KDE yields the same result.
Same error messages as reported by arne anka (in /var/log/daemon.log) Alan -- To UNSUBSCRIBE, email to debian-qt-kde-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
