Title:
  compiz crashed with SIGSEGV in malloc_consolidate()

Status in “unity” package in Ubuntu:
  New

Bug description:
  The Software Updater was wiggling in the panel (on wakeup) but
  wouldn't open when I clicked it, even from right click menu but when I
  clicked 'Install all available updates' a small progress bar appeared
  in the icon but it didn't open on the desktop, the panel  seemed to
  freeze for a few seconds, (wouldn't appear from auto-hide with mouse
  over). The Updater icon was still in the panel and green like when
  there is an update but still wouldn't open on the desktop but right
  click quit worked.
