Example file from Writer

Attached file contains some text. In deletions-on-margin mode deleting two words from two paragraphs, then accepting/rejecting all changes and undoing crashes Writer.

Steps to reproduce:
    1. Open attached file, it has some text and change tracking is enabled.
    2. Enable Options – Writer – View – Tracked deletions in margin
    3. Select a word in the first paragraph of the document and delete it
    4. Select another word in the second paragraph of the document and delete it (the problem does not happen if the two deletions are from the same paragraph!)
    5. Edit – Track Changes – Accept All or Reject All (happens with both commands)
    6. Undo

Actual results:

Expected results:
No crash.

On pc Debian x86-64 with master sources updated today + enable-dbgutil, I got an assertion but it'll crash with a non debug build I suppose considering this:
    157         assert(pTableOrSectionNode); // known pathology
    158         for (sal_uLong j = pTableOrSectionNode->GetIndex(); j <= pTableOrSectionNode->EndOfSectionIndex(); ++j)
