Get "Args out of range" on remote file loaded with tramp on emacs 27 on debian

[Steinar Bang]

Platform: debian 11 "bullseye", amd64
          GNU Emacs 27.1 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.24, 
cairo version 1.16.0) of 2021-03-28, modified by Debian

After the upgrade to debian 11, which brought me emacs 27, there are
some remote files that fail on load with "Args out of range".

There is also at least one, fairly large (1.9MB) file, that loads file
(the file used by the old gnus-sync.el).

Looking at the Messages buffer, it seems that the load fails after the
file has been fetched and successfully decompressed.

Does anyone know what causes this? And does anyone know what I can do to
fix it?

A google search on similar errors said that tramp has had it back in
2013 and 2016, but not recently.

Thanks!
