Just to clarify: by IDLE I mean not using LO application - I go off and
do other tasks on other apps. Then when I come back and resume typing
into LO it crashes. Other apps all remain stable.

gdb backtrace and all thread backtrace

remember the bug : work sometime on OOo, then do something else, come
back after a while on OOo -> crash (sometime). or do CTRL+s after having
spent sometime on other stuff -> crash(sometime).

>From my past experience, this kind of bug started first with the version 3 of openoffice. a try with IBM lotus symphony was resulting in the same crash!!!
finally I though libreoffice was not affected... but that is not the case.

I use ubuntu 10.10 (32b) when the problem started with compiz. (disabling opengl for OOO doesn't affect the bug).
I now have on ubuntu 10.10 libreoffice 3.1 and it seems not to be affected by this bug (I was not able to reproduce it).
I also recently got Ubuntu 10.04.... libreoffice 3.3 crash... 3.4 also!!!
The backtrace seems explicit... the trouble come from uno, ure. Except that is a .net like stuff, I have no more idea how it works, and what part it play in Libreoffice, OOo or lotus symphony.

However it seems related to file io with an exception badly uncatched
prducing a SIGSEGV.

My guess is that this bug should be redirected to uno framwork. Also
ubuntu distro might also play a role in it.

If you need testing for this bug, I have a document (but professional,
not to share) that seems to trigger the bug almost garanted within an
hour.

I am seeing the exact same behavior for many months, also since OOo. I
have previously submitted two gdb traces which might be useful to people
debugging this issue - below.

I am seeing this issue both in Writer and Impress very often, and it
makes working with these applications extremely unpredictable and
unpleasant. Maybe 50% of the times I start the application, I need to go
through document recovery first.

  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
