This has happened after I landed the patch in this bug: https://bugs.webkit.org/show_bug.cgi?id=50675
I decided to skip them and not to roll it out because there's no code change other than removing #ifdefs, and the paths that remained are the ones we were hitting before. This points towards a change in libsoup being the cause for these failures. Like I said before, I'm skipping them while we investigate.

As usual, I'm wrong on blaming soup ;D
