If local returned a str here and ssh a Path, should we then not also aim to harmonize the behavior of the filepath_executable property?

They both returned a pathlib.Path, the problem is that LocalTransport.isfile accepts a pathlib.Path, whereas SshTransport only accepts strings. We should probably update the transport interfaces to add support for pathlib.Path objects.

Thanks - yes, that would make sense. Up to you whether you want to do it here or not

I think it is better to do the whole interface in one go. Have opened a feature request for it #5797
If the code was attached to a `Computer` with `core.ssh` transport, the `validate_filepath_executable` would always return that the computer could not be connected to. This is because the actual exception that was caught does not come from `Computer.get_transport` but is a `TypeError` raised by `transport.isfile` since it receives a `pathlib.Path` were it expects a `str`. The problem went undetected since it only tested against a computer with `core.local` transport. A new test is added to also test against a computer with `core.ssh` transport`.
