Title:
  plymouthd crashed with SIGSEGV in free()

Status in “plymouth” package in Ubuntu:
  New

Bug description:
  Binary package hint: plymouth

  compiz, emerald and Xorg crash after executing Update Manager. I have
  no idea how this problem relates to plymouthd crashes. this issue
  occurs only when Update Manager is synchronizing the package sources
  from Internet. After the crash, Xorg offers  a list of options. some
  of them simply don't work, some crash the OS completely -- it needs to
  be rebooted, and one option starts a session with metacity (instead of
  emerald) theme manager.
