Browsing nautilus folder containing a dvi file -- apparmor/evince error

Question

If a browse a nautilus folder that contains a .dvi file, I get errors that pop onto my screen:

I think that this is due to the thumbnailer processing the file. I don't care about getting thumbnails for dvi files.

How can I stop this happening?

Answer 1

You can disable thumbnails for dvi files. Open a terminal and type the following commands:

1. Clean the thumbnails cache folder:

   rm -rf ~/.cache/thumbnails
   

2. blacklist the dvi files:

   dconf write /org/gnome/desktop/thumbnailers/disable "['application/x-dvi']"
   

3. Finally restart Nautilus:

   nautilus -q
