Is it this message?

  dumpcap: There are no interfaces on which a capture can be done

Dumpcap is printing this error through the cmdarg_err() function.  When 
dumpcap is run as a capture child of Wireshark, it sends the special 
format messages via pipes back to Wireshark.  However, when Wireshark is 
just checking the interface list, it doesn't appear to run dumpcap as a 
capture child since Wireshark isn't ready to listen for any errors 
dumpcap produces.  Compounding this problem is the fact that going to 
the interfaces in the preferences makes dumpcap print this message 
again, when it should just be ignored.
