This problem still persists in Xenial (16.04), but I may have spotted the cause. Checking my apt log, a libc upgrade had taken place before I tried to update my podcast feeds, and I hadn't since rebooted. Libc upgrades prompt for a system reboot - which I usually defer. As for #3, a reboot fixed the problem.
