PyTILE: Freeze with no debug error when scrolling through large tilesets

[Pr0nogo-zz]

Using this tileset: https://mega.nz/#F!bkoCkKpS!sOvZttkKSvguPYzrrDr-dA

Starting at the bottom of the tileset, scroll slowly at first, then accelerate until the freeze occurs. A window flashes before closing and the program freezes and must be ended via task manager.

I cant reproduce this issue on Mac, I'll try again when I build my Windows PC. Any additional info you can provide? How are you scrolling (mouse wheel, dragging scrollbar)? What is under your mouse cursor when you are scrolling? What group do you have selected when you scroll? Stuff like that.

I use the scrollbar, though it might still be possible to reproduce with mouse scroll wheel. Mouse position, group selection does not seem to matter.
