Ah.. somebody else with the problem :)

Following up on my previous testing - I was on 36-3, and 36-4 and 38-1 both
failed with that same error.  So as suggested by somebody, I scp'ed the 38-1
over to my 3800, and I got the following results from the command line:

First, try in 'test' mode - this returned *very* fast, as in sub-second:

root@bogon-gateway-1:~# sysupgrade -d 60 -v -T /tmp/openwrt-ar71xx-generic-wndr3800-squashfs-sysupgrade.bin

and no output.

So then try for real - and that worked and rebooted to 38-1 with all my config
settings preserved.  Not sure what the TRX header issue is - but it seemed to
come far too late in the process to explain my problems with Luci.

root@bogon-gateway-1:~# sysupgrade -d 60 -v  /tmp/openwrt-ar71xx-generic-wndr380

(And when it came back, it was on 38-1.

Pondering  /rom/usr/lib/lua/luci/view/admin_system/flashops.htm didn't
help much.  Down around line 83 we have this:

      <% if image_invalid then %>
             iv class="cbi-section-error"><%:The uploaded image file does not contain a supported format. Make sure that you choose the generic image format f
      <% end %>

but damned if I can figure out where/how image_invalid gets set on return
from the 'form method=post' above it....
