save as => cancel

[Matthieu Bizien]

If you click on "save as" then on "cancel" you have an exception

Traceback (most recent call last):
  File "/usr/lib/python2.6/dist-packages/perroquetlib/gui.py", line 575, in on_imagemenuitemSaveAs_activate
    self.core.Save(True)
  File "/usr/lib/python2.6/dist-packages/perroquetlib/core.py", line 319, in Save
    self.gui.SetTitle(self.outputSavePath, False)
  File "/usr/lib/python2.6/dist-packages/perroquetlib/gui.py", line 210, in SetTitle
    newTitle += " - " + title
TypeError: cannot concatenate 'str' and 'NoneType' objects

The issue is that if you click on cancel, you willn't have "" but None. So I have a patch:

class Core(object):
    def Save(self, saveAs = False):

        if saveAs or self.outputSavePath == "":
            self.outputSavePath = self.gui.AskSavePath()
            if self.outputSavePath == None:
                return

        self.gui.SetTitle(self.outputSavePath, False)
        saver = ExerciceSaver()
        saver.SetPath(self.outputSavePath)
        saver.SetVideoPath(self.videoPath)
        saver.SetExercicePath(self.exercicePath)
        saver.SetTranslationPath(self.translationPath)
        saver.SetCurrentSequence(self.currentSubId)
        saver.SetRepeatCount(self.repeatCount)
        saver.SetSequenceList(self.sequenceList)
        saver.Save()

        self.SetCanSave(False)
