...with "tcpdump -s 0 -w /tmp/capturefile", to be precise, to  
duplicate dumpcap's use of libpcap (dumpcap is run by Wireshark to do  
packet capture) and to avoid mixing printed output with error messages.

It almost certainly *will* happen with tcpdump; as indicated, the  
error comes from libpcap, used both by dumpcap and tcpdump.
