if you put a checkbox in the (Cache the media stream), the first few minutes of 
the video call goes well, then at the video there is a delay of 2 seconds or 
more, then the image starts to go bad, and the log entries appear:

Testing with Asterisk -> webrtc2sip -> sipML5 I was getting the same double 
free or corruption (fasttop) and backtrace stopped within tsk_object_delete 
method in tinySAK (doubango). Changing tsk_object_unref to call 
TSK_OBJECT_SAFE_FREE(self) instead of tsk_object_delete(self) seems to have 
fixed the issue for me. Modified source file is attached. See line 199.

It causes memleaks. But increases stability :)
