Description

The title says it, Tiled just crashes when using Ctrl + MouseWheen to zoom in or out on a map. [Here's a map I was using when I noticed this crash](https://drive.google.com/file/d/0B94sVpuHml_tV1B0SVhOMWVoMEU/view?usp=sharing)

Some maps crashes right away, others take some zooming to crash.

Research direction

Reproduce the crash on Windows x64 using the linked map and Ctrl+MouseWheel, noting whether it occurs immediately or after repeated zooming. Capture the failure details and trace the map zoom path to identify the cause; done means zooming in and out no longer crashes on the reported maps.
