It's definitely a bug. The interesting question is who is responsible for
this bug?
If it only happens with GStreamer/OSS combo and not with other OSS using
apps and if it happens on any kernel, it's pretty likely that we're at
fault. It doesn't hurt to file this as a bug in our bugzilla though I
don't think anybody from the GStreamer team has a Thinkpad so it's not
very likely that we can do something about it.
