Image item with no image in service manager possible

[Andreas Preikschat]

Hello!

1) Add a few images to the service manager.
2) Send the item live by double clicking it.
2) Click "Maintain Item" and delete all images.
3) Click "Save"

Now the image item consists of no image at all, which is odd. Of course you can add other images to the item (but does that really makes sense?).

When I double click the item in the service manager my command line throws the following errors:
Traceback (most recent call last):
  File "/usr/lib/pymodules/python2.6/openlp/core/ui/servicemanager.py", line 851, in makeLive
    self.serviceItems[item][u'service_item'], count)
  File "/usr/lib/pymodules/python2.6/openlp/core/ui/slidecontroller.py", line 511, in addServiceManagerItem
    self.onSlideSelected()
  File "/usr/lib/pymodules/python2.6/openlp/core/ui/slidecontroller.py", line 772, in onSlideSelected
    frame = self.serviceItem.get_rendered_frame(row)
  File "/usr/lib/pymodules/python2.6/openlp/core/lib/serviceitem.py", line 374, in get_rendered_frame
    return {u'main':self._raw_frames[row][u'image'], u'trans':None}
IndexError: list index out of range
