# 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.
