Package: dpkg Version: 1.4.1 Upon trying to delete a non-empty directory which dpkg presumes to be empty (such as /etc/X11/xdm) after it has deleted any files in it known to dpkg (which are not encessarily ALL files, just the ones from debian-packages) it segfaults. This does happen when it tries to install/upgrade a package.
