Need more info:

1. Which platform? Include version information, not just the name.
2. What version of gstreamer? If it's the stock version from the
package repositories of a Linux distro and you don't know the answer,
you can omit this, but you have to include the release version of the
distro then.
3. Provide your code -- at a minimum, include anything you do with
gstreamer, glib, gtk, or pthreads.

That said, a quick google suggests that you might hit this issue if
you run a GThread based app or API (Gstreamer is one such API) in a
parent process that is real-time. See

https://bugs.launchpad.net/ubuntu/+source/glib2.0/+bug/453898

and

https://bugzilla.gnome.org/show_bug.cgi?id=599079

There doesn't seem to be a clear-cut resolution accepted by upstream
yet (i.e. GLib maintainers), but what you can do is run your
application without real-time scheduling... if that works, then just
do it like that. If you think you need gstreamer to run real-time,
then you most likely should reexamine your design and either improve
performance, or reduce system load somehow, so that the pipeline
doesn't stall with normal scheduling.
