[Pkg-xmpp-devel] Bug#710688: jwchat: fails to install with apache 2.4

[Petter Reinholdtsen]

I tested using debian/maintscript, and it did not work because
jwchat.conf was missing in the package.  But I came up with another
version using code in preinst and postinst to move the old file to
jwchat.dpkg-backup in the preinst if it exist, and move it from
jwchat.dpkg-backup to jwchat.conf in the postinst if the file exist,
before calling ucf.  This seem to solve it.

I've attached the adjusted patch.

Happy hacking
