original odt file

Cross reference in .docx files are saved in some bad way and causes LO to crash.

Replication steps:
1. create .odt file with cross-reference (I attach one simple).  Insert -> fields -> more fields -> Cross-References tab, numbered Paragraph -> Number and Number (no context. Save it.
2. Save the file as .docx (I attach mine).
3. Close the docx file BUT KEEP the original odt file open (IMPORTANT to reproduce behaviour of mine).
4. Reopen the docx file (seems to be ok).
5. Tools-Update-Update all (or F9 in my case although in menu there is F8 mentioned).
6. You see the cross reference broke.

Replication steps for crashing LO:
1.-2. the same as above
3. Close the whole LO (also Quickstarter if enabled). Open the docx file from Explorer.
4. LO crashes in my case (with attached docx file).

Environment: Win7, 64bit

In version 4.4.1.? the bug did not caused a LO crash as I can remember although the bug was present. As I can remember the bug was present also in  previous version (also with doc files), but I can not provide a good version of LO (I submitted the bug for .doc file as 33893 and after fixing it I used always the .doc format as it was working till 4.3.5. After installing 4.4.1 I recognized the problem with cross reference occurred again as with doc so with docx files. has the doc problem fixed (see bug 89482), the problem persist with docx file.

On pc Debian x86-64 with master sources updated today, I opened the second file attached and had no crash.
Perhaps Windows only bug?
Comment 3 Justin L 2015-04-07 05:19:14 UTC
Unable to reproduce crashing report.  
-Linux 12.04 base, LO 4.5dev, 4.4dev
-Win XP  (no quickstart, no open LO, double-clicking on file in explorer).

Able to reproduce  "Error: Reference source not found" on various links after closing and reopening.  More show up when pressing F9.
-Linux 12.04 base, LO 4.5dev and 4.4dev
-Win XP
-NOT seen in 4.3 bibisect (not seen in git checkout latest).
-NOT seen in Win 4.3.5
Comment 4 Justin L 2015-04-07 05:59:41 UTC
-NOT seen in 4.4bibisect.

I don't have 4.5bibisect - someone else will need to continue from here.

Assigning as NEW because of the Numbered Paragraph CrossRefs that go missing when you press F9.

writer won't allow us to enter multiple CrossRefBookmarks on the same node

(Before this commit, the situation was even worse.  This is a tricky situation because LO only allows one CrossRef while MSO allows multiple.)

Thank you.
