[Message part 1 (text/plain, inline)]

Thanks. I suggest also adding a simple "version" to the cache. Whenever you
make an incompatible change in the future, bump this version. And also make
Tramp automatically discard all cached values when they come from a
different (earlier or even a later) version. Otherwise something like this
will certainly happen again sooner or later and will cost both the person
bumping into it and you or whoever responds to the bugreport a lot of time
again.
