Wow.... lots of stuff generated by -DB. I attach /var/log/audit/audit.log.

Not sure its relevant, but the only extra console-kit AVC is:

type=AVC msg=audit(1201380675.325:136): avc:  denied  { sys_tty_config
} for  pid=2728 comm="console-kit-dae" capability=26
scontext=system_u:system_r:system_dbusd_t:s0
tcontext=system_u:system_r:system_dbusd_t:s0 tclass=capability

Something else?
