Error on getimagesize when path is with custom stream wrapper

I’m migrating from an old tantan using multisite.

I upgraded to the latest version, but even before – some images can’t be parsed since getimagesize is returning with an error (Warning: getimagesize(): corrupt JPEG data: 104 extraneous bytes before marker).

I’ve tested 2 different images with/without custom stream wrappers, and just one of them came faulty, but there are more “problematic” images like this one.

I would very much appreciate any kind of help on this matter.
