Just for the record Bonjour crashes on my system anytime my net disconnects for even an instant and I've nothing else on my system that ever crashes. I honestly think Apple are terrible at software, tried safari once and it crashed every five minutes as well.
Its a system issue then, for you. Iexplorer and phoneview both work just fine here, OSX 10.7.3 and iTunes 10.5. Apple aren't terrible at software, that's a sweeping generalisation which isn't useful to you: perhaps some research and posting in http://discussions.apple.com
might help you find the source of the problem
