It's not giving me an exception. Here is the code I used:

from PyQt4.QtCore import *
from PyQt4.QtGui import *
from PyQt4.phonon import Phonon
import os
import sys, traceback

def lumberjack():
    song = '/home/tannhaus/Music/A Perfect Circle/eMOTIVE/02 Imagine.mp3'
    QCoreApplication.setApplicationName("Phonon")
    output = Phonon.AudioOutput(Phonon.MusicCategory)
    m_media = Phonon.MediaObject()
    Phonon.createPath(m_media, output)
    m_media.setCurrentSource(Phonon.MediaSource(song))
    m_media.play() 

class MainWindow(QMainWindow):
    def __init__(self, parent=None):
        super(MainWindow, self).__init__(parent)
        
        try:
            lumberjack()
        except IndexError:
            exc_type, exc_value, exc_traceback = sys.exc_info()
            print "*** print_tb:"
            traceback.print_tb(exc_traceback, limit=1, file=sys.stdout)
            print "*** print_exception:"
            traceback.print_exception(exc_type, exc_value, exc_traceback,
                              limit=2, file=sys.stdout)
            print "*** print_exc:"
            traceback.print_exc()
            print "*** format_exc, first and last line:"
            formatted_lines = traceback.format_exc().splitlines()
            print formatted_lines[0]
            print formatted_lines[-1]
            print "*** format_exception:"
            print repr(traceback.format_exception(exc_type, exc_value,
                                          exc_traceback))
            print "*** extract_tb:"
            print repr(traceback.extract_tb(exc_traceback))
            print "*** format_tb:"
            print repr(traceback.format_tb(exc_traceback))
            print "*** tb_lineno:", exc_traceback.tb_lineno
        
if __name__=="__main__":
    from sys import argv, exit
     
    a=QApplication(argv)
    m=MainWindow()
    m.show()
    m.raise_()
    exit(a.exec_())


When I run it, the complete and only error I get is:

libv4l2: error getting pixformat: Invalid argument

When I check /var/log/messages, I see these messages:
