+Bug#: 133181
+Product: GStreamer
+Version: HEAD CVS
+OS: Linux

+Status: NEW   
+Resolution: 
+Severity: major
+Priority: Normal

+Summary: filesrc crashes
+
+I get reproducable crashes in filesrc when running a lot of files 
+(usually happens around 300) through a pipeline of this kind: 
+ 
+   filesrc ! typefind ! fakesink 
+ 
+A new pipeline (and new elements) are created for every file in my case. 
+ 
+ 
+Valgrind only shows this:

+I'll attach the code that produces the problem. Compile and let loose on 
+a folder with hundreds of mp3s like this: 
+ 
+./detect /some/folde/with/mp3s
