In general, GStreamer is also thread-safe so that's unlikely the
problem :)

Can you provide a simple test case to reproduce the problem, maybe even
a standalone testcase?

What exactly is your GStreamer code doing? Maybe show the GStreamer
specific parts of it.

The stack traces look very curious, especially the last two. I assume
you're running gst_init(), otherwise it would always fail... but maybe
there is other code in your process that uses a different version of
GLib or GStreamer? It all looks very weird :)
