Application can't do anything with sprite for some reason.

[cincospenguinos]

Steps to reproduce:

1. Run SpriteEditor
2. Create a sprite.
3. Save it.
4. Watch it crash for no good reason.

It seems to be that if anything involving the Sprite variable is being done in the saveSprite() method, then it crashes. The issue magically disappeared when I jumped onto the master branch, but now it has appeared again. This makes me think that it is a code issue, not some other issue.

I was able to run the application in debugger mode, and when I pulled up the frame when getSprite() is called from CanvasWidget, I didn't see a sprite variable listed under "locals." This implies that there is some weird issue at work with the CanvasWidget. I can canoodle around some more, but what we really need is help.
