I just managed to restore X-Win functionality by renaming ~/.startxwinrc and
running the following commands, which I have now installed in permanent
postinstall scripts, to ensure that mime type and icon caches are updated:

$ head /etc/postinstall/zp_[ac]*.dash
==> /etc/postinstall/zp_all-icon-themes.dash <==
# zp_all-icon-themes.dash - rebuild all icon theme caches where index exists

if [ -x /usr/bin/gtk-update-icon-cache ]
    for index in /usr/share/icons/*/index.theme \
        /usr/bin/gtk-update-icon-cache --force $dir || :

==> /etc/postinstall/zp_cache-shared-mime-info.dash <==
# zp_cache-shared-mime-info.dash - rebuild shared mime info caches

[ -x /usr/bin/update-mime-database ] && [ -d /usr/share/mime ] && \
    /usr/bin/update-mime-database /usr/share/mime || :

You might also want to force rebuild the font cache by running:

	$ /etc/postinstall/zp_fontconfig_cache_1.sh

Take care. Thanks, Brian Inglis, Calgary, Alberta, Canada
