Description Aron Budea 2025-10-21 08:00:08 UTC 
Open attachment 96041 [details] from bug 76356 (in other name, fdo76356-1.docx), a DOCX, save it back to DOCX format, and try opening it in Word.

=> Word can't open the file cleanly.

If one:
- unzips the saved DOCX,
- executes the following command (can be done in Linux/Cygwin, needs xmllint installed): find . \( -name "*.xml" -o -name "*.rels" \) -type f -exec xmllint --output '{}' --format '{}' \;
- rezips the files with DOCX extension,

Word points to line 37 in word/document.xml, which is this line:
<w:footerReference w:type="first" r:id="rId7"/>
(rId7 refers to footer3.xml)

Observed with LO 26.2.0.0.alpha0+ (8ea8e254a3151f5390f3a10ff156fcaf8e7c5d5c), 7.2.0.4 / Windows.

This is a regression/implementation error from the following commit in 7.2, before that only a single header/footer XML was exported:
