Title: Possibly fixed crash when HOME is undefined

When HOME was undefined on Linux, the code would try calling
os.listdir(None) which will obviously fail.

This is a workaround. A proper fix would be to rewrite the
code to check for each operating system, not a combination
of operating systems, environment variables and the current
air humidity in London.

Closes issue #1025
