You can install the debug symbols seperately (e.g. install
ftp://mirror.ac.uk/sites/fedora.redhat.com/3/i386/debug/gstreamer-debuginfo-0.8.7-3.i386.rpm
)

here's gdb output, with a backtrace.

I'm getting the same problem on x86_64.  Works fine if i replace
alsasink with osssink.  alsaplayer and xmms w/alsa also work fine.

Created attachment 110398 [details]
Backtrace with all relevant debuginfo packages.

The error seems to occur because gstreamer is calling snd_pcm_hw_params before
setting the period size.  

gst_alsa_set_hw_params only sets the period size if this->format is defined. 
It sets the period size to this->period_size which seems to have a valid value
so it seems a possibile fix would be to always set the period_size, not only if
this->format is not NULL.  

Another solution that seems like it would probably work as well would be simply
to check the value of period_size->min in snd_pcm_rate_hw_refine_cchange from
alsa-libs and only use it as a divisor if it != 0

FC3 is now the responsibility of Fedora Legacy, and this does not look
like a security bug.  Can you duplicate this on FC4 or FC5, which have
a lot of updates to gstreamer and its plugins?

Closing per lack of response to previous request for information.
This bug was originally filed against a much earlier version of Fedora
Core, and significant changes have taken place since the last version
for which this bug is confirmed.

Note that FC3 and FC4 are supported by Fedora Legacy for security
fixes only.  Please install a still supported version and retest.  If
it still occurs on FC5 or FC6, please reopen and assign to the correct
version.  Otherwise, if this a security issue, please change the
product to Fedora Legacy.  Thanks, and we are sorry that we did not
get to this bug earlier.
