you are right:
type=USER_AVC msg=audit(1246817621.469:1260): user pid=1652 uid=81 
auid=4294967295 ses=4294967295 
subj=system_u:system_r:system_dbusd_t:s0-s0:c0.c1023 msg='avc:  denied 
{ send_msg } for msgtype=signal interface=org.freedesktop.NetworkManager 
member=sleep dest=org.freedesktop.NetworkManager spid=18051 tpid=1850 
scontext=unconfined_u:unconfined_r:kismet_t:s0-s0:c0.c1023 
tcontext=system_u:system_r:NetworkManager_t:s0 tclass=dbus : 
exe="/bin/dbus-daemon" (sauid=81, hostname=?, addr=?, terminal=?)'

starting kismet in enforcing mode gives me:
NOTICE: configdir '/root/' does not exist, making it.
FATAL:  Could not make configdir: File exists

Before adding more homemade rules:
I'm wondering if all other kismet users are turning off SELinux or if I 
have a special setup where the default rules of the kismet 1.2.0 module 
do not work?
Also because Dan mentioned [1] that he will add dbus rules to solve 
these denies.
The only thing that is non-standard in my config is the logtemplate 
configuration (see kismet.conf).
