Thank you for your bug report. Are you able to reproduce this crash ? If yes, could you please install libgstreamer0.10-0-dbg, gstreamer-plugins*-dbg, libglib2.0-dbg, follow https://wiki.ubuntu.com/Backtrace and attach the resulting file to this bug report. This will greatly help us in tracking down your problem.

I've just got this crash with Totem and Rhythmbox trying to play different files, so this might be a gstreamer issue.

I'll get a backtrace with debugging symbols soon.

[Emilio Pozuelo Monfort (pochu)]

BTW alsa-lib and alsa-utils were updated yesterday, so I guess this could be related to that.

[Emilio Pozuelo Monfort (pochu)]

Attached a backtrace after installing those dbg packages.

This is 100% reproducible when trying to play an mp3 file (haven't tried other formats). For example:
totem /path/to/file

[Jérôme Guelfucci (jerome-guelfucci-deactivatedaccount)]

Thank you Emilio, I think that this backtrace is not better than the previous one, maybe I forgot some debug packages... I added a gstreamer bug task and bumped this one as confirmed.

[Emilio Pozuelo Monfort (pochu)]

I upgraded alsa-utils this morning (a couple of hours ago) which was supposed to show a notification asking me to run asoundconf set-default-card. After a reboot the notification was showed, and after running that command everything works again.

[Emilio Pozuelo Monfort (pochu)]

Not a totem bug.

[Emilio Pozuelo Monfort (pochu)]

And not a gstreamer bug. If this is a bug, it's in alsa-utils. I thought it should call asoundconf in postinst, but you need to tell it which sound card you want (e.g. 'asoundconf set-default-card Intel') so this might not be possible.

[Jérôme Guelfucci (jerome-guelfucci-deactivatedaccount)]

Angel Guzman Maeso : can you confirm that what Emilio said fixes your problem ?

[Angel Guzman Maeso (shakaran)]

Sorry I have hardwork.
I install these packets but it not found gstreamer-plugins*-dbg.

I have updated and upgraded, and now totem is freeze but not appear bug report.

The url to reproduce and test is: http://www.los40.com/multimedia/player_radio.html?medio=dial
is a radiostation spanish but totem-plugin-viewer not working (on gutsy yes, but on hardy no)

[Jérôme Guelfucci (jerome-guelfucci-deactivatedaccount)]

Angel Guzman Maeso: Please try to run 'asoundconf set-default-card' and configure your default card as Emilio said to see if it fixes the issue.

Note that you first need to run 'asoundconf list' to see the list of audio cards
you have, and then pass one to 'asoundconf set-default-card', as in 'asoundconf
set-default-card Intel'.

[Angel Guzman Maeso (shakaran)]

$ asoundconf list
Names of available sound cards:
ICH6
Modem

$ asoundconf set-default-card ICH6

Still it is freeze and not working.

[Emilio Pozuelo Monfort (pochu)]

Did you restarted after that? I had to do it

[Emilio Pozuelo Monfort (pochu)]

Reopening gstreamer's task. Did I say it's not a gstreamer bug? :)

The alsa's asoundconf thing didn't work for Angel (he's just mailed me in Spanish). I can't reproduce this anymore, but hey, I don't have any evidence of this not being gstreamer's fault...

[Sebastien Bacher (seb128)]

could you try if that's still an issue in hardy or intrepid?

[Angel Guzman Maeso (shakaran)]

I cant reproduce anymore in intrepid (for now). Sorry for the delay.

[Emilio Pozuelo Monfort (pochu)]

Thanks, closing as fixed then. Please, feel free to reopen if this happens again.
