Httpd crashing

[drSteffo]

When I connect to the webGUI, I can type in my username and password. But then, it crashes.

The lighttpd error log reads:
(network_freebsd_sendfile.c.173) sendfile: Broken pipe 32
(connections.c.603) connection closed: write failed on fd 11

I'm running pfSense-1.2-LiveCD (installed on the harddrive)

My setup is:
Internet -> NIC 1 on pfsense -> NIC 2 on pfsense -> switch -> NIC on Desktop

Anyone that could help me out?
