Problem with gnome-vfs when using gdb and using gnome-vfs in a GThread

[Philip Van Hoof <spamfrommailing freax org>]

This should illustrate the problem

I also submitted this as a bug: 

	http://bugzilla.gnome.org/show_bug.cgi?id=159288


[freax lort test]$ cat test.c
#include <glib.h>
#include <libgnomevfs/gnome-vfs.h>

static gpointer thread_main_func (gpointer data)
{       GnomeVFSURI *uri = NULL;
        const gchar *source = "ftp://ftp.gnome.org/welcome.msg";;

        if (!gnome_vfs_init ())
        {
                g_print ("WARNING: GNOME VFS problems\n");
        }
        uri = gnome_vfs_uri_new (source);

        gnome_vfs_uri_unref (uri);

        g_thread_exit (0);
        return 0;
}

int main (int argc, char **argv)
{
        GThread *thread = NULL;

        g_thread_init (NULL);
        thread = g_thread_create (thread_main_func, NULL, TRUE, NULL);
        g_thread_set_priority (thread, G_THREAD_PRIORITY_NORMAL);

        g_thread_join (thread);
}

[freax lort test]$ gcc test.c `pkg-config gnome-vfs-2.0 --libs --cflags`
-ggdb
[freax lort test]$ ./a.out
[freax lort test]$

(No problems)

However.. in gdb:
