parted backtrace

Something is causing parted to backtrace. I can't get past step 3 (keyboard detection) during installation. Right before hitting next on during installation, I issued the following

ubuntu@ubuntu:/var/log$ tail -f wtmp partman apport.log auth.log kern.log debug Xorg.0.log user.log syslog messages

Which gives us

==> partman <==
