X-Debbugs-Cc: Marco d'Itri <m...@linux.it> I cannot reproduce this here. BTW: That stack backtrace is missing the actual error message which I need.
The offending line in mediastreamer2 would be this: s->dev = ms_strdup(card_data->pa_id_sink); In GDB, could you try running these commands after triggering the bug and paste the output? print s print *card_data The output of "pactl list" could also help shed some light on the cause. It could be that you have a somewhat unusual pulseaudio setup. Regards.
