Description Greg Moberg 2014-09-15 11:36:12 PDT 
For the last several weeks worth of versions up to and including WebKit r173619, Webkit has caused the downloading of numerous "Unknown" downloads of zero size. This usually happens on a page load, but sometimes at random while a page is open.

This site is a good example:

                 http://www.macobserver.com

This does not happen on standard Safari for Mac OSX. I am running Mac OSX 10.9.4, and this behavior occurs on at least 2 Macs running this version of OSX.

I could not reproduce this on OS X 10.9.4 with nightly r173638. I browsed macobserver.com for a few minutes.

So you have any Safari extensions installed? Does this still happen if you disable them?

> numerous "Unknown" downloads of zero size

Could you please confirm whether it is Unknown or Untitled? The latter name is a bit of a telltale, although that wouldn't quite explain what happened yet.
Comment 2 Alexey Proskuryakov 2014-09-19 17:12:18 PDT 
Greg, are you running the nightly with Safari 7.0.6 or Safari 7.1?

If it's 7.0.6, then the problem may well have the same root cause as bug 136953.

Greg wrote to me saying that installing Safari 7.1 resolves this.

While we don't support nightlies with anything but the very latest Safari release, this likely signifies a real regression in API. Given the regression range identified in <rdar://problem/18399291>, it must be from one of Antti's recent patches.
