Title:
  Main Window Will not Display

Status in OpenLP - Worship Presentation Software:
  Fix Committed
Status in OpenLP trunk series:
  Fix Committed

Bug description:
  I updated my local "branch" (I don't remember if that's the correct
  term or not...) to revision 2160 and tried to launch the application,
  but the main window would not open. The last few lines of the debug
  log are as follows:

  2013-01-25 21:54:12,549 openlp.core.ui.mediadockmanager                         DEBUG    Inserting Presentations dock

      sys.exit(app.run(qt_args))
    File "/home/nsmith/programming/openlp/trunk/openlp/core/__init__.py", line 137, in run
      self.mainWindow = MainWindow(self)
    File "/home/nsmith/programming/openlp/trunk/openlp/core/ui/mainwindow.py", line 567, in __init__
      self.pluginManager.initialise_plugins()
    File "/home/nsmith/programming/openlp/trunk/openlp/core/lib/pluginmanager.py", line 191, in initialise_plugins
      plugin.initialise()
    File "/home/nsmith/programming/openlp/trunk/openlp/plugins/presentations/presentationplugin.py", line 94, in initialise
      self.mediaItem.buildFileMaskString()
    File "/home/nsmith/programming/openlp/trunk/openlp/plugins/presentations/lib/mediaitem.py", line 88, in buildFileMaskString
      self.plugin.serviceManager.supportedSuffixes(type)
  AttributeError: 'PresentationPlugin' object has no attribute 'serviceManager'
  None

  I changed line 88 of the file
  "/home/nsmith/programming/openlp/trunk/openlp/plugins/presentations/lib/mediaitem.py"
  from:

  self.plugin.serviceManager.supportedSuffixes(type)

  to

  self.main_window.serviceManagerContents.supportedSuffixes(type)

  and the main window opens as expected. As I am only beginning
  development, I do not know if this is the proper remedy; thus, I am
  posting this here.

  I use Ubuntu 12.04 with LibreOffice 3.5.4.2.
