Please provide more details how to reproduce the problem: How exactly are you using Hangouts when this happens?
I'm just doing a videoconference with another people: sooner or later it crashes. google-talkplugin version is 5.4.1.0.
Maybe it has something to do with this: https://bugs.freedesktop.org/show_bug.cgi?id=79980
Does this still happens to you ?
I can't test it ATM because my Gentoo desktop needs to be fixed after some LTO/graphite tests and I don't use it since a couple of months. I will probably find some time to fix it in the next couple of months, but I'm using ony my Broadwell laptop right now. I hope Zen will be up to expectations because Intel driver is so fucking damn bugged that I can't tollerate it anymore.
P.S. Maybe we should simply close it considering how old this bug report is and not being able to test it: it has probably already being fixed.
