If I'm reading this correctly it seems that |is| here is null:

We've set it here:

... and Android's documentation mentions that this it's possible for ContentResolver.openInputStream() to return null (see the "Returns" entry):

Under 300 crashes on Fennec 68 release - I think we can classify this as a P2 based on volume. One comment: "Trying to choose an image to upload"
