This problem is not reproducible for me using an i386 lenny pbuilder chroot on amd64.
Test scenario: Outside chroot: cd /tmp # Presumably, this is the Gant icon theme referred to in the subject wget http://overlay.uberpenguin.net/icons-xfce-gant-3.9-6.tar.bz2 sudo cp /tmp/icons-xfce-gant-3.9-6.tar.bz2 /var/cache/pbuilder/build/.../root/ Xnest :10; & xauth list | grep unix:10 Inside chroot: echo "deb http://security.debian.org/ lenny/updates main" >> /etc/apt/sources.list apt-get update apt-get dselect-upgrade apt-get install xfce4 gnumeric valgrind xauth locales echo "es_AR.UTF-8 UTF-8" >> /etc/local.gen locale-gen export LANG=es_AR.UTF-8 export LC_CTYPE=es_AR.UTF-8 export XAUTHORITY=/root/.Xauthority # Allow chroot session access to Xnest started outside chroot xauth add ... export DISPLAY=localhost:10 cd /usr/share/icons && tar xvf /root/icons-xfce-gant-3.9-6.tar.bz2 xfce4-session # Xfce main menu -> Settings -> User Interface Settings -> Icon Theme -> # select "Gant for Xfce" # # Start terminal G_SLICE=always-malloc valgrind --num-callers=20 /usr/bin/gnumeric Result: gnumeric start normally. -- The road to hell is paved with telecom billing requirements. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
