The issue seems permanent, for the time being. Running a more thorough strace (attached) has revealed that the download is indeed handled by the /usr/share/lxc/templates/lxc-download binary, which unfortunately refuses to work if invoked directly by shell, so unfortunately I could not debug this particular process any further.
