Ignore binary data to avoid r_s2 stalling

[leonsodhi]

No idea how to do this, and the first step is figuring out how to reliably repro it.

I could see a default maximum of 25,000 characters per line or something. I think messages longer than that are very likely to be binary, rather than stringified JSON hashes.

@leonsodhi How big of an issue is this, still?

[leonsodhi]

Not sure. Only had one confirmed case of it although I have heard of people accidentally logging email attachments in the past. I'd be inclined to consider this low priority and leave the issue as-is. No strong opinion, though.

[johlym]

For the sake of completeness, I'd argue either doing something about it or closing it #wontfix. That's just how I roll, though.

I confirmed that it's stalling on the latest version, so I can take a look.
