Hullo Terry,
you made really a great job!!
helgrind detected some errors, but there could be some false positive.
this one seems to be a design error:

pulseaudio used by two threads, and
http://apidocs.meego.com/1.2/pulseaudio/main.html
"Threads
The PulseAudio client libraries are not designed to be directly thread-safe.
They are however designed to be reentrant and threads-aware.
To use the libraries in a threaded environment, you must assure that
all objects are only used in one thread at a time. Normally, this
means that all objects belonging to a single context must be accessed
from the same thread.
The included main loop implementation is also not thread safe. Take
care to make sure event objects are not manipulated when any other
code is using the main loop."
Hmm, why is a graphics app trying to use PulseAudio? I don't even have
it installed on any of my computers here!
