Could you explain how the backtrace implicates file-attributes? I see 
the following in the backtrace, but I don't see file-attributes listed 
there, and when I look at the tramp-handle-file-modes source it appears 
that file-attributes returned nil which is what I think you expected.

Test shadow-test08-shadow-todo backtrace:
  signal(args-out-of-range ("([] 1)"))
  tramp-signal-hook-function(args-out-of-range ([] 1))
  tramp-mode-string-to-int(nil)

tramp-handle-file-modes(#("/mock:localhost:/build/shadowfile-tests75GTBI" 
6 15 (tramp-default t)))
  apply(tramp-handle-file-modes 
#("/mock:localhost:/build/shadowfile-tests75GTBI" 6 15 (tramp-default t)))
  tramp-sh-file-name-handler(file-modes 
#("/mock:localhost:/build/shadowfile-tests75GTBI" 6 15 (tramp-default t)))
  apply(tramp-sh-file-name-handler file-modes 
#("/mock:localhost:/build/shadowfile-tests75GTBI" 6 15 (tramp-default t)))
  tramp-file-name-handler(file-modes 
#("/mock:localhost:/build/shadowfile-tests75GTBI" 6 15 (tramp-default t)))
  file-modes(#("/mock:localhost:/build/shadowfile-tests75GTBI" 6 15 
(tramp-default t)))
