xchat-gnome crashed with SIGSEGV in g_hash_table_foreach()

[Li Li <eggonlea gmail com>]

Hi all,

I met a segfault issue with xchat-gnome in Ubuntu Oneiric.

The following small patch fixes the segfault when network status is changing.

--- xchat-gnome-0.30.0~git20100421.29cc76.orig/plugins/net-monitor/net-monitor.c
+++ xchat-gnome-0.30.0~git20100421.29cc76/plugins/net-monitor/net-monitor.c

+		if(networks)
+			g_hash_table_foreach (networks, (GHFunc) connect_to_network, NULL);
 	}
 }

Please find more details here:
