firestarter closed unexpected (GLib-GObject-CRITICAL)

[yordy]

firestarter start and is't closing...

[root at tux ~]# firestarter 
Firewall started

(firestarter:6915): GLib-GObject-CRITICAL **: g_object_remove_weak_pointer: assertion `G_IS_OBJECT (object)' failed
Segmentation fault
[root at tux ~]#

there is any other frontend for iptables like firestarter?

Greetings
