Description:
Creating a new document or saving an modified existing one, the created file is created with wrong file permissions.

All files are created as user rw only. Before existing group rw flags are disapearing.


Steps to Reproduce:
1. open a file odt or other libreoffice document, in our case on NFS Share and set up group sticky bit above the curren dir

[jojo@pc6 O-20180828-010]$ umask
0002
[jojo@pc6 O-20180828-010]$ ls -la
drwxrwxr-x 1 leander firma    206 28. Aug 11:09  ./
drwxrwxr-x 1 leander firma     54 28. Aug 10:33  ../
-rw-rw---- 1 jojo    firma 404180 28. Aug 11:03 'O-20180828-010.odt'

2. edit and save

[jojo@pc6 O-20180828-010 Servertausch]$ /usr/lib/libreoffice/program/swriter 'O-20180828-010.odt' 
[jojo@pc6 O-20180828-010 Servertausch]$ ls -la
-rw------- 1 jojo  firma 404180 28. Aug 11:09 'O-20180828-010.odt'


3. permissions of the freshly edited file are forgotten and set to user only.

Actual Results:
[jojo@pc6 O-20180828-010 Servertausch]$ /usr/lib/libreoffice/program/swriter 'O-20180828-010.odt' 
[jojo@pc6 O-20180828-010 Servertausch]$ ls -la
-rw------- 1 jojo  firma 404180 28. Aug 11:09 'O-20180828-010.odt'


Expected Results:
[jojo@pc6 O-20180828-010 Servertausch]$ /usr/lib/libreoffice/program/swriter 'O-20180828-010.odt' 
[jojo@pc6 O-20180828-010 Servertausch]$ ls -la
-rw-rw---- 1 jojo  firma 404180 28. Aug 11:09 'O-20180828-010.odt'



Reproducible: Always
