Could be the latter, yes. "tmpdir" is the only cache value I know of
which has changed its meaning(*). Perhaps I shall add a test that it
ignores cached "tmpdir" values if they are remote. But hmm, it has
changed its meaning also in Tramp 2.5.3.2, which is distributed via GNU
ELPA.

(*): More precisely, there were two different meanings in different
places of Tramp. The fix was needed to fix that bug.
