It crashes with the following error if I don't put it in an idle handler =================================================================================================== (run:14061): GStreamer-CRITICAL **: Trying to dispose element autoaudiosrc0, but it is in PLAYING instead of the NULL state. You need to explicitly set elements to the NULL state before dropping the final reference, to allow them to clean up. This problem may also be caused by a refcounting bug in the application or some element.
