Title:
  compiz crashed with SIGSEGV in __dynamic_cast()

Status in “unity” package in Ubuntu:
  New

Bug description:
  Nothing too strenuous from a compositing point of view - typing in a
  terminal and the display paused while compiz crashed. Have had similar
  occurrences before but bug submissions rejected because packages were
  out of date. I did an update and hour ago so fingers crossed not
  again.
