What in all actually is this PDF attachment doing with the newsletter?

enter image description here

I'm fairly confident that this also came from Stack Exchange, so would someone care to enlighten me as to what's going on? I admit I'm rusty at reading mail headers, but the sources seem to line up just fine.

    @rene: As interesting as that may be, I can't deduct asdasd in...whatever currency that is from my bank account right now. I mean, I am going on a business trip soon, so I've gotta keep a bit of cash in the bank for souvenirs...

    This appears to be an XY problem, and you are asking the wrong question. What you should be asking is, "What the dues is what the deese how the doesn't doesn't dues?". Please show us how you determined that the doesn't doesn't dues, and what you have deesed to determine does does (or doesn't) the dues. We're not here to do your work for you.

    I got a feeling this wasn't really supposed to reach production and be sent. Mar 20, 2015 at 20:14

The PDF in question is linked to from this question in the form of a drive.google.com link. Judging by the sample newsletter, the question was included in the newsletter you received.

enter image description here

Gmail autodetects Google Drive links, and adds them as friendly attachments*.. which causes crazy in this particular, albeit pretty rare, instance.

* You can test this by including the link https://drive.google.com/file/d/0B6HXMKHljcfYV1d5Yl9YNzd4TWM/view?usp=sharing, and sending it in an email to yourself, like I did

    Nice work tracking this one down. What a hilariously bizarre occurrence.

    Darn it Inbox...Thanks for the answer. Strangely enough it did this with a newsletter that had a YouTube link, but it didn't register with me that it was GMail/Inbox being overzealous with its visibility.
