LiipImagineBundle imagine_filter not working

Question

I have a problem with the imagine_filter that works in one page and not in the others even if I use it exactly the same way with the same photo.

In the first page, where my filter works, I have this src: http://myserver.com/media/cache/shooting/photo_preview/75/55cb71cc8ba26-00001.jpg

However, on the page where the filter doesn't work, I have this src:

:///media/cache/shooting/photo_preview/75/55cb71cc8ba26-00001.jpg

Has anybody already have a problem like that?

Moreover, the first src only works on app.php and not on app_dev.php.

On my application, I'm using Gaufrette to upload photos to S3 and then Liip to apply the filters. The cache is on my server. This is my configuration:

"liip/imagine-bundle": "1.3.*@dev",
"knplabs/gaufrette": "0.1.*",
"knplabs/knp-gaufrette-bundle": "0.1.*@dev",
"aws/aws-sdk-php": "2.8.*@dev",

I got an answer on Github. I just needed to change my resolver:
