H.323 connection tracking code calls ip_ct_refresh_acct() when processing RCFs and URQs but passes NULL as the skb. When CONFIG_IP_NF_CT_ACCT is enabled, the connection tracking core tries to derefence the skb, which results in an obvious panic. A similar fix was applied on the SIP connection tracking code some time ago.
