I get this message:

diskinfo can't open 
/home/olpc/.sugar/default/data/f70f03b1-fe40-44e6-9d75-5ef274cf0ad2.wav

The file path is correct, and refers to beats.wav from the Csound distro 
(copied to my XO-1.5 via the Journal).

My file chooser function is:

 def choose1(self, widget):
  chooser =  ObjectChooser(parent=self, what_filter=mime.GENERIC_TYPE_AUDIO)
  result = chooser.run()
  if result == gtk.RESPONSE_ACCEPT:
    jobject = chooser.get_selected_object()
    if jobject and jobject.file_path:
      self.filename[0] = str(jobject.file_path)
#      open(self.filename[0]).read()
#      open(object.file_path).read()
  else:
    self.filename[0] = "0"

I receive the message whether I use either of the "open" lines or neither.

The filename is being passed (successfully, as "file1") to my .csd by this 
line:

   self.w.set_filechannel("file1", self.filename[0])

FWIW, I get the following WARNING earlier in my log:

1289234354.334491 WARNING root: Invocation of ObjectChooser() has deprecated 
parameters.
/usr/lib/python2.6/site-packages/dbus/connection.py:242: DeprecationWarning: 
object.__init__() takes no parameters
  super(Connection, self).__init__(*args, **kwargs)
1289234358.752408 WARNING root: DSObject was deleted without cleaning up 
first. Call DSObject.destroy() before disposing it.

I've assumed that this has nothing to do with my problem, but perhaps I am 
wrong. The *complete* ObjectChooser() function is listed above. (The 
ObjectChooser() call is in the format recommended by a member of the 
sugar-dev list.)

You should also check the specific types of the filenames provided and
of the argument expected. Sometimes there are different kinds of
strings, or objects that evaluate to strings in some contexts and not
in others.

Hope this helps,
Mike
