This problem only occurs once under windows vista. Seems that some component is misbehaving/misusing he windows directory separator. It only occurs with empty data/temporary directory. Adding the following code in F3\FLOW3\Resource\Streams\ResourceStreamWrapper, line 499 to change windows style backslash to slash solved the problemfor me. Of course there should be a smarter fix.
$requestedPath = str_replace('\\', '/', $requestedPath);
