This is solved in 2.4b1+debian-21.1 (upstream, pangolin). The package is nearly identical, and urlsnarf is seriously broken in debian-21. Recommend backporting.

(The bug is that the pcap-file and live-capture logic are reversed, so running a live-capture looks for a pcap file and crashes, and using a pcap file tries to do a live capture).
