Description:
------------
Use Phar::decompressFiles() to decompress files in a phar where files was compressed with Phar::compressFiles(Phar::GZ) throw an exception.

Configure Command =>  './configure'  '--with-layout=GNU' '--with-config-file-scan-dir=/usr/local/etc/php' '--with-mysql=mysqlnd' '--with-mysqli=mysqlnd' '--enable-libxml' '--with-libxml-dir=/usr/local' '--with-pcre-regex=/usr/local' '--program-prefix=' '--disable-cgi' '--with-apxs2=/usr/local/sbin/apxs' '--with-regex=php' '--with-zend-vm=CALL' '--disable-ipv6' '--prefix=/usr/local' '--mandir=/usr/local/man' '--infodir=/usr/local/info/' '--build=i386-portbld-freebsd8.0'

Test script:
---------------
<?php

mkdir(__DIR__ . '/files');

for ($file = 1; $file < 50; $file++)
{
	file_put_contents(__DIR__ . '/files/' . $file . '.php', '<?php echo \'' . str_repeat($file, 5000) . '\'; ?>');
}

$phar = new \Phar(__DIR__ . '/compressed.phar');

$phar->buildFromDirectory(__DIR__ . '/files', '/\.php$/');
$phar->setSignatureAlgorithm(\Phar::SHA1);
$phar->compressFiles(\Phar::GZ);

for ($file = 1; $file < 50; $file++)
{
	unlink(__DIR__ . '/files/' . $file . '.php');
}

rmdir(__DIR__ . '/files');

$phar = new \Phar(__DIR__ . '/compressed.phar');

$phar->decompressFiles();

foreach ($phar as $file)
{
	var_dump(file_get_contents($file->getFilename()));
}

?>

Expected result:
----------------
No output and phar was decompressed.

Actual result:
--------------
