------- Comment #4 from Tim-Philipp Müller  2007-03-12 21:55 UTC -------
Some comments after looking at the debug log:

1) One of the first few lines is this:

(process:12563): GStreamer-WARNING **: The GStreamer function
gst_init_get_option_group() was
        called, but the GLib threading system has not been initialised
        yet, something that must happen before any other GLib function
        is called. The application needs to be fixed so that it calls
           if (!g_thread_supported ()) g_thread_init(NULL);
        as very first thing in its main() function. Please file a bug
        against this application.

This is something that's fixed in current gnome-media versions. Please update
or apply the (very straight-forward) g_thread_init() fixes from SVN trunk (2
commits, check the ChangeLog). This is pretty much a prerequisite to exclude
random memory corruption by the GLib GSlice allocator as a cause of issues,
hence the warning.



2) The log contains these warnings/errors from ALSA:

ALSA lib confmisc.c:670:(snd_func_card_driver) cannot find card 'intel'
ALSA lib conf.c:3500:(_snd_config_evaluate) function snd_func_card_driver
returned error: No such device
ALSA lib confmisc.c:391:(snd_func_concat) error evaluating strings
ALSA lib conf.c:3500:(_snd_config_evaluate) function snd_func_concat returned
error: No such device
ALSA lib confmisc.c:1070:(snd_func_refer) error evaluating name
ALSA lib conf.c:3500:(_snd_config_evaluate) function snd_func_refer returned
error: No such device
ALSA lib conf.c:3968:(snd_config_expand) Evaluate error: No such device
ALSA lib pcm.c:2145:(snd_pcm_open_noupdate) Unknown PCM default
ALSA lib confmisc.c:670:(snd_func_card_driver) cannot find card 'intel'
ALSA lib conf.c:3500:(_snd_config_evaluate) function snd_func_card_driver
returned error: No such device
ALSA lib confmisc.c:391:(snd_func_concat) error evaluating strings
ALSA lib conf.c:3500:(_snd_config_evaluate) function snd_func_concat returned
error: No such device
ALSA lib confmisc.c:1070:(snd_func_refer) error evaluating name
ALSA lib conf.c:3500:(_snd_config_evaluate) function snd_func_refer returned
error: No such device
ALSA lib conf.c:3968:(snd_config_expand) Evaluate error: No such device
ALSA lib pcm.c:2145:(snd_pcm_open_noupdate) Unknown PCM default

This might be an issue in the ALSA library or with the alsa config files, but
doesn't look like a GStreamer issue.



3) It doesn't look like a crash happened while taking the log; the last lines
of the log indicate controlled/clean shutdown of the alsamixer element. What
would be much more useful is a debug log from when the crash actually happens.
