crash in notifications

[Rodrigo Moya <rodrigo gnome-db org>]

Hi

[This is GConf for GNOME 2]

I'm not sure if I'm doing something wrong, but the GConf notifications
stuff is crashing my program all the time. The crash is when I set up a
GConf key which has listeners on it. Here's the backtrace:

Program received signal SIGSEGV, Segmentation fault.

For setting up the notifications, I use:

	gconf_client_add_dir (get_conf_client (), path, 			     
GCONF_CLIENT_PRELOAD_NONE, NULL);
        listener_data->id = gconf_client_notify_add (
                get_conf_client (),
                path,
                (GConfClientNotifyFunc) config_listener_func,
                listener_data->user_data,
                (GFreeFunc) g_free,
                &err);

get_conf_client just returns a pointer to a static GConfClient. The code
that causes that crash is just a call to gconf_client_set_string.

Am I doing something wrong? Is it a bug in GConf? If so, I'll add a bug
to bugzilla with this backtrace, if you want.

cheers
