Hi, I'm new to sofia and I'm playing with the sofsip demo application
(version 0.16) to get familiar with the stack and a fully functional
example.
But I'm having an error, which I can't figure out how to fix. In one of
the clients (I'm running 2 clients in different boxes) I get this error:
** (<unknown>:28760): CRITICAL **: priv_update_tx_elements: assertion
`self->sm_udpsink != NULL' failed
Then I can't see any RTP traffic between the 2 boxes (I can see the SIP
signaling, which seems fine). At the end I pasted the complete log for
both clients.
Also, in the box I get that error, I can only run sofsip under GDB,
otherwise I get a SIGSEGV with this backtrace:

I hope it is OK to ask about problems with sofsip here. Any pointers
would help, since I'm not familiar either with sofia, sofsip or
gstreamer.
Thank you.
