--- Comment #3 from nyxkn@yahoo.com --- It is indeed related to the voice chat. From what I can tell the crash happens when the green halo appears around people's portraits to indicate they're talking. It's not a complete crash, in that it just causes the client UI to reload. While that happens, voice chat is still working, and you are not disconnected. But of course timers are still going and you can miss the match found dialog or the champion lock in time limit. Once you make it into the game, voice chat works without issues. A trick is to disable the automatic voice chat joining and only connect to voice chat while in game.
I'll try to acquire some logs if I get a chance.
