Thanks to Norbert’s debug version of LibreOffice 3.6.0.2+, I spent several
hours trying to reproduce all the different kinds of crashes which are
mentioned in this bug report and in all its duplicates. For this I used MacOS X
10.6.8 (Intel) with "Enable access for assistive devices" checked in the System
Preferences and RightZoom running (cf. comment 44). Now here is a quick
overview of my results -- which, I fear, are not as helpful as I had expected.
But only the developers can tell.

(1) and (2) I can NOT reproduce two kinds of crashes specific to Impress (bug
47569 and bug 50147). What regards the latter one (sorting slides), this could
be explained by bug 51023, which currently makes sorting slides in LibO 3.6.x
on MacOS mostly impossible, and therefore may also "hide" bug 50147.

(3) I can reproduce the crash in the LibreOffice Preferences (application
"Options") window (bug 44807, bug 52147, and probably bug 37913). See my
comment in bug 52147. For this crash, I got two slightly different kinds of
crash logs, see attachment 64599 and attachment 64600.
  Good news, I hope: both contain explicte references to Accessibility stuff,
e.g. XAccessibleContext, XAccessibleComponent, XAccessibleAction. So it may be
helpful to look into these log files. I can investigate more, if you want and
tell me what to do ...

(4) As said above (comment #55), I can NOT reproduce the crash which occurs on
setting character color and character background color (bug 51686 etc.), and I
think -- but I may be totally wrong -- that this has to do with the new bug
51943. See comment #55, again.

(5) and (6) But I can reproduce a crash with two similar color-setting related
actions (cf. comment #0 in this report):
  When I open Writer and add a background color to a paragraph (via Format >
Paragraph) or to a table (Via Table > Table properties...), LibO crashes. NB:
It may be necessary to click forth and back through the different tabs of the
"Paragraph" or "Table Properties" dialog before to get the crash.
  On both crashes, I get nearly identical log files -- see attachment 64594,
and my comments in bug 51686. Both log files are also more or less identical
with Norbert’s log file, cited here in comment #45.

(7), (8), (9) Many bug reports speak about crashes when adding a border to a
cell in Calc or to a paragraph in Writer, or when changing border properties --
see this present report (comment #0), and bug 50467 and bug 51791.
  I can reproduce this crash in at least three ways: in Calc, when I add a
border to a cell (see attachment 64555); in Writer, when I add a border to a
paragraph (see attachment 64590) or when I change the border width of a table
(see attachment 64592). Cf. my comments in bug 50467.
  All three log files are very similar, and they are more or les identical to
attachment 64594 from point (5) above and to Norbert’s log file (comment #45).
All these log files don’t contain explicte references to Accessibility stuff
(but only the developers can really judge this). So these crashes seem to have
all the same technical background.

(10) I can reproduce a freeze or crash related to auto-filter in Calc -- this
is bug 47275 and bug 52342. See my comments in bug 47275. The log file for the
freeze (attachment 47275) could be especially interesting, because it contains
explicte references to Accessibility stuff. The crash log (attachment 47275)
may be less interesting (no Accessibility stuff?), but only our developers can
judge this.

That’s it -- my results of several hours spent with making LibreOffice crash, a
rather destructive pastime ;-) Hope it helps a bit ...
