 As far as I can see, it leaks less than before, but still leaks 
 massively, with CVS HEAD from 2004-March-09.

+Some more information: 
+ 
+I think the 'mad' element that is created when running the  
+ 
+        filesrc ! typefind ! spider ! fakesink 
+ 
+pipeline on an mp3 file is never disposed of when the pipeline gets 
+destroyed. 
+ 
+Here's what I did to come to that conclusion: 
+ 
+static gpointer maddata;  /* NULL */ 
+static gpointer pipedata; /* NULL */ 
+ 
+static void 
+ea_cb (GstBin *spider, GstElement *element, gpointer foo) 
+{ 
+  g_print("ELEMENT ADDED: %s\n", gst_element_get_name(element)); 
+  if (strncmp(gst_element_get_name(element), "mad", 3) == 0) 
+  { 
+    g_print ("hooking up nullifier...\n"); 
+    maddata = spider; 
+    g_object_set_data_full(G_OBJECT(element), "madfoo", &maddata, 
+(GDestroyNotify)g_nullify_pointer); 
+  } 
+} 
+ 
+..... 
+ 
+g_signal_connect(spider, "element-added", ea_cb, NULL); 
+ 
+gobject_set_data_full(G_OBJECT(pipeline), "pipefoo", &pipedata, 
+(GDestroyNotify)g_nullify_pointer); 
+ 
+...... 
+ 
+after the pipeline is unrefed, pipedata will be NULL, but maddata 
+will still be some non-NULL value, so the mad object didn't get 
+destroyed. 
+ 
+I am not sure if that would cause huge leaks like that, but it's 
+worth a shot. 
+ 
+Hope this helps whoever is debugging this further :) 
+ 
+Cheers
