            Bug ID: 135356
           Summary: Unwanted change in filesystem ownership when saving
                    documents
           Product: LibreOffice
           Version: 6.4.5.1 rc
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Base
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: pgl at otenet.gr

Description:
When LibreOffice saves documents, it changes their file permissions. This
behaviour:

a) messes with the workflow in my household, where we share one big disk, have
unix users for each member, and a 'family' unix group, which allows us to e.g.
edit all sorts of files owned by other members in the 'family' group

b) goes against what I perceive as standard practice (that personal files'
ownership and permissions should only be changed when the users request such a
change), though I'm not sure if there's any standardization document that
supports this claim

Steps to Reproduce:
1. Create any document with default unix permissions of anyuser:anyuser
2. Change the group of the document, e.g with `chown anyuser:anygroup document`
3. Save the document (tested it with both Writer and Calc)

Actual Results:
Ownership is now `anyuser:anyuser`

Expected Results:
Ownership should still be `anyuser:anygroup`


Reproducible: Always


User Profile Reset: Yes
