I think the game crashes if you start to download a new version then lock your computer while it's going.
What I expected to happen was...:
When I came back, Minecraft would be open and running
What actually happened was...:
I saw a crash report in the launcher
Steps to Reproduce:
1. Begin downloading a new minecraft version (might occur when just launching)
2. Lock your computer (WinKey + L on Windows) (I'm ona alptop, I actually pressed Fn+f7 which turns off the screen and has a similar effect)
3. After a period of time, unlock your computer.
