Permission error saving a file - on CIFS mount (fstab)

Submitted by MichaelB

Description

Hi,

I refer to the bug originally posted on launchpad by Alex D in 2016. https://bugs.launchpad.net/ubuntu/+source/evince/+bug/1567565

Short resume here:

It is impossible to SAVE (overwrite) the opened pdf file when this file is in a CIFS mount point (fstab). It appear a permission error.. and much more bad, the file is totally erased!!

Tested on different version from Evince 3.18 and now on Ubuntu 17.10 (Evince 3.26.0) and problem persist!

Example usage: We are in a company environment, files are mounted by SMB in a mount point (fstab). We want open a pdf file, add annotations and save the file (overwrite). Not possible...

Please try to correct this major problem for a company daily usage.. and for the upcoming Ubuntu 18.04 LTS.

Thanks!
