rhythmbox with local python

fixed a mysterious problem with rhythmbox. it was giving me segfault immediately on startup, along with some other (apparently unrelated) clutter.

** (rhythmbox:5239): CRITICAL **: atk_object_set_name: assertion `name != NULL' failed

** (rhythmbox:5239): CRITICAL **: atk_object_set_name: assertion `name != NULL' failed

and complaints about pygtk. i thought i could fix it by putting pygtk from the system python in my PYTHONPATH, but no joy. only by taking my local python bin out of the PATH would it work.
