++Subject: [PATCH] agent: fix parsing an incomplete TCP ICE candidate
++
++If a TCP ICE candidate mline in a SDP doesn't specify the `tcptype`
++field, it was crashing the agent because of the non-null assert in
++`g_ascii_strcasecmp`. The patch is just ignoring an incomplete TCP
++candidate just like the other malformed candidates.
