MapDust plugin crashing after deleting a layer.

[rickmastfan67]

Steps to reproduce:

1. File > Download from OSM
2. Select an area to download in the "Slippy Map" window (doesn't matter what size) and download.
3. Once the data is downloaded, delete "Data Layer 1". DO NOT START MAPDUST FROM THE LEFT AT ANY TIME!

Expected results:
MapDust's plugin doesn't crash.

What happens?:
MapDust crashes without having been activated at all from the left (or via the shortcut).
