Comment 8 for bug 1826468

Description:
After upgrading from Ubuntu 18.10 to 19.04 Libreoffice lost its ability to write to network drives. In my case it's a DAVS system, which I connect to using Nautilus. I access the file on the drive with Nautilus, open a file by double-clicking it, it opes without problems, I can change it and save it, but I cannot export the document as PDF or "Save As" another document at the same location. I get one popup window saying: "Error saving the document <document name>: Nonexistent file" and after closing it another one opens with "Error saving the document <document name>: General error. General input/output error".

The problem seems to emerge from time to time, as this example shows:
https://bugs.launchpad.net/ubuntu/+source/libreoffice/+bug/1069757

Steps to Reproduce:
1. Map a network drive through Nautilus
2. Access a LibreOffice document on this drive, open it by double-clicking it
3. Try to export the document as PDF to the same location or try to save it under another name without changing the location of the file

Actual Results:
one popup window saying: "Error saving the document <document name>: Nonexistent file" apperars and after closing it another one opens with "Error saving the document <document name>: General error. General input/output error".

Expected Results:
The software should export a file or write it down under a new name.

Reproducible: Always
