SELinux is preventing abrt-action-gen from map access on the file 2F686F6D652F6D696B6861696C2F2E6C6F63616C2F73686172652F537465616D2F737465616D617070732F636F6D6D6F6E2F496E7465727374656C6C6172204D6172696E65732F496E7465727374656C6C61724D6172696E65732E783634.

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

If you believe that abrt-action-gen should be allowed map access on the 2F686F6D652F6D696B6861696C2F2E6C6F63616C2F73686172652F537465616D2F737465616D617070732F636F6D6D6F6E2F496E7465727374656C6C6172204D6172696E65732F496E7465727374656C6C61724D6172696E65732E783634 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 'abrt-action-gen' --raw | audit2allow -M my-abrtactiongen
# semodule -X 300 -i my-abrtactiongen.pp
