Slavek,

dm.h:40:   #define WITH_CONSOLE_KIT

** there is NO conditional surround this define, it is defined always.

dm.h:488: #ifdef WITH_CONSOLE_KIT
dm.h:489: int StartClient( const char *ck_session_cookie );
dm.h:490: #else
dm.h:491: int StartClient( void );
dm.h:492: #endif

client.c:1205: #ifdef WITH_CONSOLE_KIT
client.c:1206: int
client.c:1207: StartClient( const char *ck_session_cookie )
client.c:1208: #else
client.c:1209: int
client.c:1210: StartClient()
client.c:1211: #endif

client.c:1311: env = setEnv ( env, "XDG_SESSION_COOKIE", ck_session_cookie );

session.c:642: #ifdef WITH_CONSOLE_KIT
session.c:643: 	ck_session_cookie = open_ck_session (getpwnam(curuser), d);
session.c:644: 	if (!(clientPid = StartClient(ck_session_cookie))) {
session.c:645: #else
session.c:646: 	if (!(clientPid = StartClient())) {
session.c:647: #endif


Even without consolekit installed on the system, this still causes StartClient
to be declared as:

  int StartClient( const char *ck_session_cookie );

instead of

  int StartClient( void );

and client.c causes StartClient to be initialized with the character pointer
ck_session_cookie (hopefully NULL) and part of the XDG_SESSION_COOKIE
environment to be set (if not NULL).

It may not matter, but it does not seem like good practice to leave code like
that hanging around in the absence of concolekit. I have put fprintf statements
inside all WITH_CONSOLE_KIT preprocessor conditionals and will report back with
which ones are being executed..
