This is for git branch 0.11, compiled today.

1. I tried this in two ways - using Gobject Introspection and command line
pipeline. GI version looked like this (this is simplified part of Jokosher
port):

from gi.repository import Gst
Gst.init(None)
clickTrackAudioSrc = Gst.ElementFactory.make("audiotestsrc",
"Click_Track_AudioSource")
self.clickTrackAudioSrc.set_property("wave", 3) (at this point I got segfault)

Command line pipeline looked like this:

/data/opt/gnome/bin/gst-launch-0.11 audiotestsrc wave=1 ! fakesink

2. I got segfault and when running command line pipeline within jhbuild
enviroment, I got suggestion to attach gdb to the process which I did.

3. After attaching I get bt who looked like this:
