[patch for 3.5.X] proposal of a patch to solve a crasher when saving a spreadsheet with track-change

Hello,

The crasher my colleague Pierre-Éric solved as been pushed to master,
thanks Eike, thanks a lot for that :-)
https://bugs.freedesktop.org/show_bug.cgi?id=51249

Because this patch fixes a crasher, I would like to know if it would be
possible to review it for the 3.5.X series.

Thanks a lot,


Lionel
