TypeError: stream.resume is not a function

[clochix]

A user is reporting that he's unable to access some of its folders.
Having a look at the logs, there are a lot of error 500 when trying to get the thumbnails.

Here are the logs:

/usr/local/cozy/apps/files/build/server/controllers/files.js:488
     stream.resume();
            ^
TypeError: stream.resume is not a function
  at LaterStream.callback (/usr/local/cozy/apps/files/build/server/controllers/files.js:488:14)

and

/usr/local/cozy/apps/files/build/server/controllers/files.js:521
     stream.resume();
            ^

stream is a LaterStream that has no resume method, only pipe and abort.
The error returned by getBinary is Error code 404 - {"error":"Not Found"}

@aenario any thought?
