Torbrowser crashes if it can't DNS resolve the Socks5Proxy host in torrc
Using Torbrowser 6.0.6 on OS X Yosemite.
When in the office behind our corporate firewall I configure Torbrowser to use our socks5 proxy.
When at home Torbrowser crashes on launch.
If I delete the Sock5Proxy line from torrc it works.
If I put a dummy entry for my office socks proxy host in /etc/hosts torbrowser doesn't crash.
Tor should trap a failed DNS resolve when validating the proxy config on launch and tell the user that it can't connect to the internet.
