this is not a bug
mounting a remote filesystem locally "imports" it so it is available to userland programs like a local directory.

It appears to return incorrectly for 'file://' wrapper which I would consider to be local.

CODE:
$file1 = '/somefile.jpg';
$file2 = 'file://shouldbelocal.jpg';
$file3 = 'http://someotherfile.jpg';

$local = stream_is_local($file1);
$shouldbelocal = stream_is_local($file2);
$remote = stream_is_local($file3);
var_dump($local, $shouldbelocal, $remote);

RESULT:
bool(true)
bool(false)
bool(false)

<?php
$file1 = '/somefile.jpg';
$file2 = 'file://shouldbelocal.jpg';
$file3 = 'http://someotherfile.jpg';
$file4 = 'file:///indeedlocal.jpg'; // Please note '///' instead of '//'

$local = stream_is_local($file1);
$shouldbelocal = stream_is_local($file2);
$remote = stream_is_local($file3);
$indeedlocal = stream_is_local($file4);
var_dump($local, $shouldbelocal, $remote, $indeedlocal);

The function stream_is_local() does not work with remote mounts points, like sshfs mount points (it will return true as if it was local).
