Hello, I don't reproduce this issue, tests pass on my laptop. Can you debug why it fails and submit a PR if you find something to fix?

[flip111]

I don't know how to debug this, please advise.

I can't reproduce this anymore, i will reopen and try to look around in the fileystem at the time this error occurs.

Oh actually i can reproduce this .. i had another project with Finder that doesn't clean up. I'll try to find the problem and make Finder a bit more resilient.

About the FinderTest .. all paths are hardcoded, should they stay like that or can the right paths be searched? For example ..

symfony/src/Symfony/Component/Finder/Tests/FinderTest.php

Lines 330 to 352 in d8739d1

	$this->assertIterator($this->toAbsolute(array(
	'.git',
	'foo',
	'foo/bar.tmp',
	'test.php',
	'test.py',
	'toto',
	'toto/.git',
	'.bar',
	'.foo',
	'.foo/.bar',
	'.foo/bar',
	'foo bar',
	'qux',
	'qux/baz_100_1.py',
	'qux/baz_1_2.py',
	'qux_0_1.php',
	'qux_1000_1.php',
	'qux_1002_0.php',
	'qux_10_2.php',
	'qux_12_0.php',
	'qux_2_0.php',
	)), $finder->in(self::$tmpDir)->getIterator());

the thing is that by changing the fixture all the test cases need to be updated. It's tedious
