Please describe the problem:
This was reported on Launchpad: https://bugs.launchpad.net/ubuntu/+source/ekiga/+bug/112948
by: https://bugs.launchpad.net/~durdon-tyler

When using pulseaudio as soundserver, ekiga hangs when calling someone.

Steps to reproduce:
1) The audio wizard works with the pulseaudio settings (alsa emulation, default device)
2) Call someone


Actual results:
When the other side answeres the phone, ekiga hangs (does not respond any more)

Expected results:
Retry with normal alsa: everything works

Does this happen every time?
Yes

Other information:
Backtrace: http://launchpadlibrarian.net/8295832/gdb-ekiga.txt

asound.conf file :

pcm.pulse { type pulse }
ctl.pulse { type pulse }
pcm.!default { type pulse }
ctl.!default { type pulse }

In Gutsy, terminal outputs:

ekiga: pcm_params.c:2351: sndrv_pcm_hw_params: Assertion `err >= 0' failed.
Aborted (core dumped)

This also seems to happen with skype.
