- libventi: fix segfault in vtreadpacket when not connected This problem happens especially in fossil/view when vtread can be called even if not connected to venti. The old libventi handle this case properly in the function vtRPC, which is called by vtReadPacket (client.c). R=rsc CC=plan9port.codebot http://codereview.appspot.com/5484044
