Description of problem:
Bash command: `$/usr/sbin/unhide sys' returns numerous libgcrypt messages:

libgcrypt selftest: pubkey RSA (1): mismatch (encrypt)
libgcrypt selftest: pubkey RSA (1): Selftest failed

Sometimes `$firefox' returns them once when launched from bash.

While checking with rkhunter for hidden processes, it prints warnings in /var/log/rkhunter/rkhunter.log with the same lines from libgcrypt, where it suppose to report PIDs of found hidden processes.

firefox package ver. 36.0-1.fc21.x86_64

Additional info:
SSSD used for system login/authentication with

 [domain/default]
 ldap_schema = rfc2307bis
 ldap.uri=ldap://localhost.localdomain

after some troubles with SELinux preventing Login service from start with direct LDAP database connection without SSSD.
Problems begun right after libgcrypt update from ver. 1.6.1-7 to ver. 1.6.3.-1
