Thank you for your bug report. This bug has been reported to the developers of the software. You can track it and make comments at: https://bugzilla.gnome.org/show_bug.cgi?id=603795

[Nigel Babu (nigelbabu)]

Upstream reports that its a pulseaudio bug and not an empathy bug, changing accordingly.

[C de-Avillez (hggdh2)]

Marking as INCOMPLETE, right now. We need to know *where* Empathy/PA were when we had this assertion failure.

@Kersian: how familiar are you with low-level debugging? I mean using GDB, and downloading as many debug packages as may be needed.

[C de-Avillez (hggdh2)]

@Kersian: could you please set
enable-shm = no

in ~/.pulse/daemon.conf

or (if the above file does not exist) in /etc/pulse/daemon.conf, and then try again?

Thanks

[Kersian (kersian)]

Sorry for the time dudes, University is killing me with stupid assembler exercises!

I tried setting enable-shm = no, and I managed to get sound in the conversations, but when a video chat is started, crashes again leaving this:

Ok, so there definitely is a PulseAudio component, but I can't tell
immediately if it's due to some SHM bogosity on your system (linux
problem? eglibc problem?)

Please confirm that using enable-shm = no at least makes sound events
audible in empathy and runs stably. That latter point is vital.

As for your video problem, there is:
empathy-MESSAGE: 1.260107e+09: Element error: Cannot identify device
'/dev/video0'. -- v4l2_calls.c(482): gst_v4l2_open ():
/GstPipeline:pipeline3/EmpathyGstVideoSrc:empathygstvideosrc3/GstGConfVideoSrc:gconfvideosrc3/GstBin:bin38/GstV4l2Src:v4l2src2:
system error: No such file or directory

[Kersian (kersian)]

I have had a chat with my gf's laptop and I can definately hear her voice. A bit distorted but not bad.

About the video issue, I can't get to see her, as soon as the conection stablishes it crashes if there is video in it.

[Daniel T Chen (crimsun)]

Can you reproduce this in Lucid?

[David McCallum (dmccallum9)]

I am able to reproduce this bug in lucid.

1) Run gnome-volume-control from the terminal

2) Move to the hardware tab

3) Wait a few seconds

I obtain: Assertion 'b' failed at pulsecore/memblock.c:451, function pa_memblock_acquire(). Aborting.
Aborted

[Daniel T Chen (crimsun)]

David M, would you (if you haven't already) file a separate bug
against the sound driver using "ubuntu-bug alsa-base" in Applications
> Accessories > Terminal ?

[Dan Kegel (dank)]

For what it's worth, I can reproduce David M.'s assertion by starting Dragon Age Origins
on my system under wine-1.3.16.
There seem to be two workarounds:
1) run the app in question under "taskset 1"
-or-
2) put enable-shm = no
in ~/.pulse/daemon.conf

[Daniel van Vugt (vanvugt)]

Thank you for reporting this bug to Ubuntu.
