[Andreas Preikschat <andreaspreikschat@xxxxxxxxxx>]

Andreas Preikschat has proposed merging lp:~googol/openlp/image-queue into lp:openlp.

Requested reviews:
  Tim Bentley (trb143)

For more details, see:
https://code.launchpad.net/~googol/openlp/image-queue/+merge/107549

Hello,

- stop the imageManager when closing OpenLP (when you add some images and close OpenLP when in debug mode, you might get a traceback about log being None or the like).

Your team OpenLP Core is subscribed to branch lp:openlp.
