Maybe it's windows-exclusive, I don't know as I don't use any apple device.
I could reproduce it on my notebook: after clicking on labels, theme, labels, it crashed. My notebook runs Windows 7 Professional 64 Bit (Lenovo Thinkpad X1 Carbon, Intel Core i5, 8GB RAM, 256GB SanDisk SSD), my PC runs Windows 8.1 Professional 64 Bit (self-built, Intel Xeon, 32GB RAM, GTX 980, 256GB Crucial MX200, 3TB Seagate Barracuda).
