Description
Steps to reproduce
Running Ubuntu 16.04.4 LTS (via WSL):
$error.Clear()
Import-Module /mnt/c/[tab][tab][tab][tab][tab][tab][tab]
#then clear the command line and run
$errorExpected behavior
No problems, you just get tab completion for stuff under your C drive.
Actual behavior
You don't get any tab completion. For as many times as you hit [tab], you have an error like this in $error:
Exception calling "CompleteInput" with "3" argument(s): "Access to the path '/mnt/c/hiberfil.sys' is denied."
