Thanks for the bug report. This does seem to be a genuine, and long-standing, bug: an older version of draw-tree that I compiled some time ago fails on your "tree" input, while copy-tree works so it should be a valid input.
This is not urgent, though, since draw-tree is not actually needed for any Kaldi workflow. So I'll wait to see if someone (possibly @vdp if he is feeling like a diversion at some point) wants to deal with this. But it's not urgent at all.
