Hi Sam,
We see the following error in the traces:

Unfortunately, the call of the shell function tramp_perl_file_attributes
redirects stderr, so we don't know exactly what happened.
Checking the relevant code, I've found a potential problem in Tramp's
cache handling. Not sure whether it is related to your problem, but I've
committed the following patch to the master branch:

Could you, pls, check whether this cures the problem already? If not, we
need more information why the shell function fails. Pls apply the
following patch:

Afterwards, rerun the test until it fails, with tramp-verbose set to
10. Maybe we will know better then what happens.
Best regards, Michael.
