I use pulseaudio provided with openSUSE 12.1: pulseaudio-1.1-1.2.i586 package. However starting pavucontrol (any: system-supplied or self-compiled) results in blinking "Volume Control" window and segmentation fault. I'm assigning this report to "pavucontrol", please re-assing if this should be "core" or sth else.

() Backtrace stopped: Not enough registers or memory available to unwind further The #0 line is not fully printed above, so I've checked pdispatch.c for the source. It looks like that: pa_assert_se(r->time_event = pd->mainloop->time_new(pd->mainloop, &tv, timeout_callback, r));

Is there any other additional info I can provide?
