The scaling factor is what caused the crash on my machine. By default it
is 200 % and this makes Ubiquity crash. Changing to 100 % (even just
before validating last input panel) prevents it from crashing.

Obviously this a bug.

Title:
  Ubiquity crashed during install of 18.04 with error 'BadAccess
  (attempt to access private resource denied)'

Status in ubiquity package in Ubuntu:
  Incomplete

Bug description:
  Ubiquity consistently crashes during install.
  I use the "Something else" option.
  It crashes after I've entered the user information and clicked Next.
  No error message is displayed.

  If I try to restart Ubiquity, I get a dialog with the message "ubi-
  partman failed with an exit code 10." If I click the dialog's try
  again button, I get the same message.

  My system is broken, and I am only able to install 17.10.1.

  $ sudo dmidecode | grep -A 9 "System Information"
