Description Myers Carpenter 2006-06-02 00:44:00 UTC 
Run the gstfile.py example a few times any file and you will get this error message:

*** glibc detected *** corrupted double-linked list: 0x0819f610 ***
Aborted


I loaded python into gdb and ran it again.  There were 5 threads running and this is the backtrace:

(gdb) bt

+ Trace 68595

I'd welcome any other tips on how I could provide more debugging info.

Here is one file that I can get it to happen with:

could you try again with cvs of gst-python ? I think this issue by the following commit : 

2006-04-29  Edward Hervey  <edward@fluendo.com>

	* examples/gstfile.py:
	Threaded application, we NEED gobject.threads_init().
	This should finally gets rid of the crashes when used on single files.
Comment 2 Myers Carpenter 2006-06-02 13:13:46 UTC 
While I didn't check out the latest CVS, I added gobject.threads_init() to the top of my copy of gstfile.py and ran it a 50 times with "watch -n 0.5 python gstfile.py rage2.avi" and it did not have the same problem.

I think you can close this bug!

Thanks,
