I can not follow your problem. Using the current development versions (and also 2.1.0 and 2.2.0 versions) of the two software libraries dom-crawler and css-selector, the example code you provided works just fine considering the following example HTML:
```
<?php
use Symfony\Component\DomCrawler\Crawler;

// require dependencies here    

$html = <<<'HTML'
<!DOCTYPE html>
<html>
    <body>
        <p class="message">Hello World!</p>
        <p>Hello Crawler!</p>
        <div id="product">
            <a data-type="bla">
                <img src="OK">
            </a>
        </div>
    </body>
</html>
HTML;

$crawler = new Crawler($html);

$link = $crawler->filter('#product a[data-type="bla"]');

echo var_dump(count($link));

var_dump($link->filter('img')->attr('src'));
```
As you can see this is exactly your code (only a little different but essentially not), which gives the following output verbatim:
```
int(1)
string(2) "OK"
```
The first output line is the count() and the second is the src attribute value.

Have you run composer update? Have you double-checked the input?
