[Björn Michaelsen <bjoern.michaelsen@xxxxxxxxxxxxx>]

Lets reiterate the current status:
- This only happens on an machine under heavy load with data on ecryptfs
- the stacktrace show:
  a) this to happen at various locations (the stacktraces are different).
  b) even more important: some of the stacktraces show things, that cant possibly be, if the underlying system works correct.
See the linked upstream discussion of this between me and Caolán McNamara.
Quote:
"The bug report's stack is from svx autocorrect, which means that ucbhelper::cancelCommandExecution and cppu::throwException have successfully thrown exceptions at least a hundred times or so before the crash, so its not the case that it's e.g. the first throw or two through the uno bridge."
this means that the following: 
"With an eip of 0x100000 (in the i386 bug reports) meaning the call goes into nirvana." 
cant really happen unless there is some serious memory corruption around (or the stacktraces themselves are wrong, however in general, they look sane). The  eip == 0x100000 is in a lot of stacktraces here while it should be a random (and different) number (pointing to the created ExceptionThrower object) instead.

As of now, there is _no_ indication that Libreoffice itself is at fault. it might demonstrate the problem more clearly, because:
a) it is such a big project.
b) such crashers appear to be random noise in other projects.

@penalvch: I am not very happy about the setting of the bug state to
confirmed again without discussion. My change was quite intentional
given the above evidence. At least it needs to be set back to
"Incomplete" until something shows Libreoffice to be at fault in this
IMHO. To prevent a bug-state-war I will ask bugcontrol to have a look at
it and leave state as is for now.

  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

  WORKAROUND: Use Gnumeric.
