Comment 5 for bug 706354

In a very quick analysis I found that all the packages (on my system) that use "if dpkg-maintscript-helper supports ..." are affected.

daniel@daydream:~$ grep dpkg-maintscript-helper /var/lib/dpkg/info/*.postinst | grep support
/var/lib/dpkg/info/apparmor.postinst:if dpkg-maintscript-helper supports rm_conffile; then
/var/lib/dpkg/info/libreoffice-common.postinst: if dpkg-maintscript-helper supports rm_conffile; then
/var/lib/dpkg/info/libreoffice-common.postinst: if dpkg-maintscript-helper supports mv_conffile; then

/var/lib/dpkg/info/ntpdate.postinst:if dpkg-maintscript-helper supports mv_conffile; then
