Not sure if the bug I experienced is similar, but I got this SELinux warning when I opened a PDF file in Evince (and I've seen more warnings related to evince-thumbnailer, too):
SELinux is preventing /usr/bin/evince-thumbnailer from search access on the directory 1684.
***** Plugin catchall (100. confidence) suggests ***************************
If you believe that evince-thumbnailer should be allowed search access on the 1684 directory by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep evince-thumbnai /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
