--- Comment #1 from Carlos Garcia Campos <cgarcia at igalia.com> ---
I've found the problem, and it's not a Soup issue (soup is not even used for Blobs), but GTK+ specific one. The problem is that GTK+ API uses URIs for download destination paths, and passes that uris to the WebKit internals. But WebKit expects download destination location to be a local path. This is not a problem for normal downloads, because the soup backend handles the cases of download destination being a URI and a path. For blob downloads NetworkDataTaskBlob is used, and it always expects the download destination to be a local path, failing in FileSystem::openFile() when a URI is passed. We need to keep using local files internally and convert to URIs only when exposing those paths to the API.
