mythfrontend only caches the icon for you. Something else retrieves it
on the backend--mythfilldatabase or channel_icons.pl. Likely that
something else didn't have permission, so it failed, so the icon image
doesn't exist. Or, for a combined frontend/master backend system, the
files exist but aren't readable by the frontend process, so it tries to
save a "local" copy and fails (because someone else owns a file in that
