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

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

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

  I think this crash may have been behind some windows for awhile.  It
  was there along with another crash for Ubuntu Tweak closing
  unexpectedly.  I had tried to remove a duplicate repository source in
  Ubuntu Tweak and it seemed to hang indefinitely. I hit the exit button
  and Ubuntu Tweak seemed to close normally.  I was able to remove the
  source later using the source editor in synaptic successfully and also
  install other software; so i know that it did not lock up my package
  manager.
