Description of problem:
SELinux is preventing geary from 'map' accesses on the fifo_file fifo_file.

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

If you believe that geary should be allowed map access on the fifo_file fifo_file 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:
# ausearch -c 'geary' --raw | audit2allow -M my-geary
# semodule -X 300 -i my-geary.pp
