Description of problem:
SELinux is preventing abrt-hook-ccpp from using the 'sigchld' accesses on a process.

*****  Plugin mozplugger (99.1 confidence) suggests   ************************

If you want to use the plugin package
Then należy wyłączyć kontrolę SELinuksa nad wtyczkami Firefoksa.
Do
# setsebool -P unconfined_mozilla_plugin_transition 0

*****  Plugin catchall (1.81 confidence) suggests   **************************

If jeśli abrt-hook-ccpp powinno mieć domyślnie sigchld dostęp do procesów z etykietami kernel_t.
Then proszę to zgłosić jako błąd.
Można utworzyć lokalny moduł polityki, aby umożliwić ten dostęp.
Do
można tymczasowo zezwolić na ten dostęp wykonując polecenia:
# grep abrt-hook-ccpp /var/log/audit/audit.log | audit2allow -M mojapolityka
# semodule -i mojapolityka.pp

This is what I got on a fresh f22 install with all updates installed:

SELinux is preventing abrt-hook-ccpp from using the 'sigchld' accesses on a process.

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

If si crede che abrt-hook-ccpp dovrebbe avere possibilità di accesso sigchld ai processi etichettati kernel_t in modo predefinito.
Then si dovrebbe riportare il problema come bug.
E' possibile generare un modulo di politica locale per consentire questo accesso.
Do
consentire questo accesso per il momento eseguendo:
# grep abrt-hook-ccpp /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

It's not related to firefox, I get it on this machine and in a test VM, where firefox is not running. I ran the command advised and left it there.
