Description of problem:
SELinux is preventing /usr/bin/totem-video-thumbnailer from unix_read, unix_write access on the shared memory .

*****  Plugin catchall (100. confidence) suggests  ***************************

If you believe that totem-video-thumbnailer should be allowed unix_read unix_write access on the  shm 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 multiqueue0:src /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
