That usually happens with me every time as well. I just log in again, when you see a blank screen after logging in again, hit enter and you will see the installer again depending on where it crashed. While annoying, it has never prevented me from getting through the install and I know the password pretty well after three or four times of having to log in.
Unrelated but useful is the fact that you can log in as root, set up all your interfaces, log out, log in as installer and install and it will install with the network set up the way you wanted, namely ip. This way you can log into the ip right away when it reboots via web browser. I never use 192.168.1.x as the lan network, some modems use 192.168.1.1 as their ip as well as other things, everyone can't be 192.168.1.1 and not everything uses DHCP by default.
