Description of problem

I always get : "NoneType object has no attribute get_width" error whenever I select a snapshot. the image of that snapshot doesnot show.

also the snapshot apply button below is disabled. But sometimes I still can apply snapshots by right clicking and selecting the snapshot.

recently, I got an error while applying a snapshot (by right click and select) and from then, everytime I restart my VM, that snapshot gets automatically applied, removing all my data that were used after that.
