+Subject: [PATCH] avahi: core: extract host name using avahi_unescape_label()
+
+Previously we could create invalid escape sequence when we split the
+string on dot. For example, from valid host name "foo\\.bar" we have
+created invalid name "foo\\" and tried to set that as the host name
+which crashed the daemon.
+
