Hi, The following code: --------------------------------------------------------------- DBusError e; DBusConnection *conn = NULL; g_type_init (); dbus_error_init(&e); conn = dbus_bus_get(DBUS_BUS_SESSION, &e); -------------------------------------------------------------------- causes: 3896: assertion failed "(error) == NULL || dbus_error_is_set ((error))" file "D:\kde\distfiles\svn-src\dbus-src\tags\1.2.4\dbus\dbus-sysdeps-win.c" line 3159 function _dbus_get_autolaunch_address Backtrace: 4牋牋牋 KiFastSystemCallRet 3牋牋牋 WaitForSingleObject+0x12 3牋牋牋 dbus_print_backtrace+0x94 3牋牋牋 dbus_abort+0xb 3牋牋牋 dbus_real_assert+0x46 3牋牋牋 dbus_get_autolaunch_address+0x2b3 3牋牋牋 dbus_transport_open+0x550 3牋牋牋 dbus_transport_open+0x11e 3牋牋牋 dbus_connection_close+0xe52 3牋牋牋 dbus_bus_register+0x3fd 3牋牋牋 RegisterWaitForInputIdle+0x49 -> when the dbus-daemon is not running I think it's not a normal behavior. It's hard to test it on ubuntu (for example) because a lot of process needs this daemon (so you may not want to kill it), but on win32 it's easy to reproduce it. version 1.2.4-1 Should i report a bug ? Note that I 'm new to dbus so maybe I am doing something wrong. Sincerely Julien
