  I last used KPackageKit to do a full update (selected all and clicked apply) two weeks ago.  Everything was fine. I then went on vacation for two weeks

  This evening, after returning from vacation, I ran another full
  update, and things went very wrong after that.  It seems compositing
  somehow got turned on. (???)  Compositing won't work on my system.
  The result was very ugly.  (eventually I got a message telling me that
  compositing had been turned off, as it was to slow, and things got
  much better after that!)

  So I tried systemssettings -> Look & Feel -> Desktop and it crashed.
  I tried and tried and tried and it crashed every time.  Even after a
  full shutdown and boot.  I tried using the KDE Crash Handler to report
  this, but each time I tried to Install Debug Symbols I got a dialog
  saying "Could not find debug symbol packages for this application."
  So here I am.

  Here is the info I copied from the KDE Crash Handler "Developer
  Information" Tab:
