/*
* This file reproduces the bug in the bugreport #143777, as can be seen at
* http://bugzilla.gnome.org/show_bug.cgi?id=143777 - the issue is that when
* pausing a pipeline while the chainhandler is still running, then unlinking
* the pad that's chain function is called and relinking it clears the buffer
* that was stored for sending the event. gst_pad_call_chain_function needs
* to check that.
* The fix is in gstpad.c, revision 1.327
