master_port.c:143: pjmedia_master_port_stop: Assertion `m && m->clock' failed.

[Niclas.Bengtsson@xxxxxxxx (Niclas Bengtsson)]

Hi,
 
I get this error when i try to hangup my call with
pjsua_call_hangup_all();
 
../src/pjmedia/master_port.c:143: pjmedia_master_port_stop: Assertion `m
&& m->clock' failed.
 
Running on arm and using the pjsua layer.
 
Anyone have any ideas what could be wrong?
 
Regards,
Niclas
