Title:
  update-apt-xapian-index crashed with SIGSEGV in memcpy()

Status in “apt-xapian-index” package in Ubuntu:
  Confirmed

Bug description:
  Binary package hint: apt-xapian-index

  This was a fresh installation of the Beta 2 from and ISO that I made
  myself from the Ubuntu Beta 2 Release page.  I just updated and
  installed everything today.. and this happens as soon as I boot the
  system each time.   Usually around the time I try to first run Firefox
  4 maybe?  Not too sure.  Firefox 4 and Adobe Flash are extremely
  unstable.  I get sound distortion and choppy playback.  I didn't have
  these problem with 10.10.  Just that I should let you know.
