Which of the two pipelines are you interrupting?

It's probably a bug in one of the GStreamer elements involved.

I would recommend you run gst-launch in a debugger such as gdb (or get a
core dump) to see where the error comes from:

 $ gdb --args gst-launch-0.10 ...
 (gdb) run
 ... wait for abort ..
 (gdb) thread apply all bt
 ... show us this..
 (gdb) kill
 (gdb) quit

(Note: use gst-launch-0.10 not gst-launch when debugging things,
gst-launch is a wrapper binary, which will mess up traces).

 Cheers

PS: you should ideally move to GStreamer 1.x
