Comment 3 for bug 1097437

PROBLEM DESCRIPTION:
LibO crashes when accepting a change tracked change after having increased the number of undo steps and being at the end of the previously configured undo stack

STEPS TO REPRODUCE (not yet "optimized" - maybe there's a shorter path):
1. create a new, empty writer document, write some lines with arbitrary text.
2. open the preferences dialog, go to the memory (german „arbeitsspeicher“) part and set the number of undo-steps to five.
3. save the document somewhere and close the document
4. re-open the document
5. enable change tracking („änderungen aufzeichnen“ in German)
6. make six arbitrary, isolated changes to the document (change tracking should mark the changes)
7. click „undo“ as often as possible (should be five) and do not do anything else after that (don't even move the cursor – I'm not sure if that matters but that was my way to reproduce)
8. open the preferences dialog, go the memory part and increase the number of undo steps to ten.
9. right-click on any of the remaining changes with markup from change tracking and choose „accept change“ („Änderung akzeptieren“ in German)
10. -> Immediate Crash of LibreOffice

CURRENT BEHAVIOR:
crash (document is recoverable)

EXPECTED BEHAVIOR:
 - no crash
 - change is accepted
 - accepting the change can be undone
