Comment(by jpichon):

 Thank you for the feedback. I was so keen on removing the stack trace and
 displaying an error message that I didn't properly check the validity of
 the message itself, sorry! It looks like the directory paths for
 TamTamEdit are hardcoded incorrectly in sound.py. Installing TamTamEdit
 doesn't work for the "Getsound" example either, I'm looking into it at the
 same time.

 Is there a recommended way to access activity directories from Sugar? I've
 had some success with adding the following to finddir() in sound.py so
 far, though I still need to test it further and on different
 configurations:

 {{{
     tamtam_dir = "TamTamEdit.activity/common/Resources/Sounds/"
     if "SUGAR_PATH" in os.environ:
         dirs.append(os.environ["SUGAR_PATH"] + "/activities/" +
 tamtam_dir)
     dirs.append(os.path.expanduser("~") + "/Activities/" + tamtam_dir)
 }}}
