Title:
  plymouthd crashed with SIGSEGV in script_obj_deref_direct()

Status in “plymouth” package in Ubuntu:
  New

Bug description:
  I initially created a file /etc/xorg.conf with a typo in Driver and restarted:
  Section "Device"
     Identifier "Intel Graphics"
     Drive "Intel"
     Option "DRI" "False"
  EndSection

  which naturally brought me to a blinking cursor in the top left. After
  booting into recovery mode, fixing the typo, and restarting, a
  plymouth crash notification appeared.
