It looks like it's the version check for Python Live errors failing. It's odd, because it almost looks like it fails only when the current directory is the network directory hosted by sshfs-win. What happens if you cd to the network directory that holds that python file, and run "/usr/bin/python3 --version" from there? Do you get any errors or any output?
As a temporary workaround, go to the Options dialog, and go to Languages -> Scripting Languages -> Python -> Live Errors, and change the profile from <Auto Detect> to Pylint3. That should make it so it doesn't have to do the version checks.
I'll take a closer look at the code for this. Probably need to make sure to run the "python --version" in a known local directory, to avoid any unecessary network accesses for network drives.
