starting point close to the segfault

Here is an easier way to show the segfault.  I am calling it the same
segfault because of the similarity of the top five frames in the
backtraces.

(1) Download and open the attached file undo_segfault.odt.  The caret
    is at the end of the text in row 2 column 2 of the table.

(2) Type "<tab>".  The program adds row 3 to the table.

(3) Type "<ctrl>+Z".  SEGFAULT.


This happens on master commit b092637, fetched 2012-12-06 17:20 UTC,
configured:
    --enable-option-checking=fatal
    --enable-dbgutil
    --enable-crashdump
    --without-system-postgresql
    --without-myspell-dicts
    --with-extra-buildid
    --without-doxygen
    --with-external-tar=/home/terry/lo_hacking/git/src
built and and running debian-wheezy.

For comparison, LibreOffice supplied with debian-wheezy, version
3.5.2.4 (Build ID: 350m1` (Build:2)), places the cursor at the start
of row 1 cell 1 when it opens the file.  I have to move the cursor
first. Then "<tab><ctrl>+Z" correctly adds row 3 to the table and
removes it again.  So, I am setting keyword "regression".

The crash is not evident in bibisect versions
    40 oldest
    40+ latest
I take this to indicate that the crash is peculiar to debug builds,
and I conclude that the failed attempts to replicate the problem on
Win and OSX do not indicate very much.  (Of course, the all-nines
value of `this` in frame zero of the backtrace is peculiar to a debug
build.)  So, I am setting Whiteboard "NotBibisectable".
