  3) What is expected to happen in a KDE Natty in a KDE session with the
  KDE integration active or GNOME is a Writer or Calc file untouched for
  a long period of time (ex. 1 hour+) is when one tries to edit it, the
  application does not crash.

  4) What happens instead is it crashes. This is highly correlated to
  both EcryptfsInUse and resource constrained (Memory & CPU >> 50%)
  environments. Occurs with:

  + Intel drivers, Compiz not enabled, Writer open only bug 745836
  + binary ATI drivers, Compiz enabled, Calc open only bug 799047
