Comment:
I had exactly the same problem when i tried to add wav-files. After
removing python-gst-0.8.3-1 and keeping python-gst0.10 serpentine at
least began to load the wav-files until it crashed.

Here's the output with python-gst-0.8.3.1 installed:

On the second attempt (with --debug option) and third attempt (normal
run without --debug option) adding of the wav-files worked.

Perhaps the crash on the first attempt without python-gst-0.8.3-1 was a
result of an old python-gst instance still in the cache.

Nevertheless, serpentine either needs a version-checking for python-gst
or should conflict with < python-gst-0.10
