Comment 5 for bug 1539080

I unfortunately can't reproduce this on demand. I've had it happen to me so far twice, both times immediately after resume, on two completely different wifi networks, once on a mobile hotspot from my phone and another time at a hotel in Brussels.

My best guess is that it's got to do with some network state at suspend time which then causes breakage on resume.

If I do find some kind of pattern that I can use to even vaguely reproduce this thing on request, then I'll definitely send you a trace.
