Thanks. I have used TCPDump to capture traffic during the request to update
a feed in gPodder; and, for comparison, during download of the same feed
URL in the Epiphany web browser.
$ sudo tcpdump -i wlan0 -s 1500 -w
~bignose/gpodder-download.20121221.tcpdump
tcpdump: listening on wlan0, link-type EN10MB (Ethernet), capture size 1500
bytes
[… use gPodder to “Update podcast” …]
^C29 packets captured
29 packets received by filter
0 packets dropped by kernel
[… close gPodder …]
$ sudo tcpdump -i wlan0 -s 1500 -w
~bignose/epiphany-download.20121221.tcpdump
tcpdump: listening on wlan0, link-type EN10MB (Ethernet), capture size 1500
bytes
[… use Epiphany to download the same URL reported by gPodder for the feed …]
^C38 packets captured

I then used Wireshark as instructed, to filter HTTP packets in each of
these dumps.
There are *no* HTTP packets in the TCPDump capture during the gPodder
session. The only traffic captured at all is from my IRC client; gPodder
appears to have generated no traffic.
The Epiphany session has two HTTP sessions; one for the feed, and one for
the site's favicon. The feed request has the following header:
=====

and the response has this header:

So the document is fetched fine, using Epiphany (which uses GNOME's network
and proxy settings). But gPodder doesn't even seem to be trying?
