Analysing the backtrace, it doesn't look like "this change" is
responsible. It seems rather that this is the first sign that Paul's
recent changes have damaged Tramp. I mean, that file-attributes returns
an error now instead of nil, if a file is not accessible.

My analysis could be wrong, but the question still stands: why do we
need this change in file-attributes and friends?

(And I propose to start with a new bug. It is not related to
shadowfile-tests at all).

Best regards, Michael.
