php - opening image with Imagine gives 'An image could not be created from the given input'

Question

I'm using Imagine to resize images after uploading them with curl in /tmp:

$_imagine = new \Imagine\Gd\Imagine();
$mode = \Imagine\Image\ImageInterface::THUMBNAIL_INSET;
$image = $_imagine->open($path); // i.e $path = '/tmp/photo.jpg'
// then resizing the $image

It is working fine with any previously uploaded images in my /tmp, but when uploading this image http://newsimg.bbc.co.uk/media/images/67373000/jpg/_67373987_09f1654a-e583-4b5f-bfc4-f05850c6d3ce.jpg then trying to open it with Imagine, it gives the following error:

Fatal error: Uncaught exception 'Imagine\Exception\InvalidArgumentException' with message 'An image could not be created from the given input'

Did anybody know what is wrong with this image that makes it throw this exception?

here is the print_r(getimagesize($path)); as asked by @hakre:

Array
(
    [0] => 464
    [1] => 261
    [2] => 6
    [3] => width="464" height="261"
    [bits] => 32
    [mime] => image/x-ms-bmp
)
