Description:
When I try to open files shared to me over NFS in Libre Office Writer, this silently fails. If I copy the files to local storage the files open fine. In the syslog I see messages about an apparmor FAIL. Messages are shown below in the "Additional Information" box.

Steps to Reproduce:
1. Install or upgrade to 1:5.4.5-0ubuntu0.17.10.1 on Ubuntu 17.10
2. Share files over NFS to this machine
3. Open any Writer file.

Actual Results:  
Silent failure with syslog messages as below.

Expected Results:
Files should open.


Reproducible: Always


User Profile Reset: Yes


OpenGL enabled: Yes
