Description:
------------
As for my testing, FilesystemIterator fails with the foreach loop while the while-next loop works as expected.

Test script:
---------------
<?php
$iterator = new \FilesystemIterator(
	'/fuse-filesystem',
             \FilesystemIterator::CURRENT_AS_SELF
           | \FilesystemIterator::SKIP_DOTS
);
echo "--while\n";
while($iterator->valid()) {
	echo $iterator->current()."\n";
	$iterator->next();
}
$iterator->rewind();
echo "--for\n";
foreach ($iterator as $entry) {
	echo $entry->getFilename()."\n";
}


Expected result:
----------------
--while
.hg
file1.class.php
file2.class.php
--for
.hg
file1.class.php
file2.class.php


Actual result:
--------------
--while
.hg
file1.class.php
file2.class.php
--for
