This leads to the following error:

Debugger entered--Lisp error: (user-error "Method ‘archive’ is not known.")
  signal(user-error ("Method ‘archive’ is not known."))
  tramp-error((tramp-file-name "archive" nil nil "file%3A%2F%2F%2Fhome%2Flarsi%2FDownloads%2F4672362..." nil "" nil) user-error "Method `%s' is not known." "archive")
  apply(tramp-error (tramp-file-name "archive" nil nil "file%3A%2F%2F%2Fhome%2Flarsi%2FDownloads%2F4672362..." nil "" nil) user-error "Method `%s' is not known." "archive")
  tramp-user-error((tramp-file-name "archive" nil nil "file%3A%2F%2F%2Fhome%2Flarsi%2FDownloads%2F4672362..." nil "" nil) "Method `%s' is not known." "archive")
  tramp-dissect-file-name("/archive:file%3A%2F%2F%2Fhome%2Flarsi%2FDownloads%...")
  tramp-file-name-handler(expand-file-name "" "/archive:file%3A%2F%2F%2Fhome%2Flarsi%2FDownloads%...")
  file-name-case-insensitive-p("")
  abbreviate-file-name("")
  ibuffer--abbreviate-file-name("")

The problem seems to stem from tramp throwing an error when calling
`abbreviate-file-name' in the *tramp/archive...* buffer.  Perhaps
Michael knows why; added to the CCs.
