Using this script:

$file = '/etc/group'; // just some file.. :)
$file2 = './foo.bz2';

$handle = fopen ($file, "r");
$handle2 = bzopen($file2, "a"); // 'w' works fine
$buffer = fread($handle, 8192);
if(!bzwrite($handle2, $buffer, strlen($buffer))) {
        echo "Foo\n";


The first run (when foo.bz2 does not exist) produces this error: 

Warning: bzwrite(): supplied argument is not a valid stream resource in /home/jani/t.php on line 8

Second run (foo.bz2 exists) -> Hangs.
