# XXX Currently, elementtidy segfaults when there are no error, because of
# the behavior of libtidy.
# A patch has been sent to Debian:
# http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=576343
#
# As it is not integrated in Debian yet, and as this problem persists on other
# systems, using elementtidy is for now to avoid.
