Still reproducible with current master on OS X Mojave 10.14.1.  Command line:

$ arm-softmmu/qemu-system-arm -M raspi2 -append "console=ttyAMA0,115200 
root=/dev/mmcblk0p2 rootwait rw" -cpu cortex-a7 -dtb bcm2709-rpi-2-b.dtb -drive 
file=2018-11-13-raspbian-stretch-lite.img,if=sd,format=raw -kernel kernel7.img 
-m 256m -no-reboot

The stack trace looks pretty self-explanatory ("NSWindow drag regions should 
only be invalidated on the Main Thread!"); probably a manifestation of 
https://bugs.launchpad.net/qemu/+bug/1802684 
<https://bugs.launchpad.net/qemu/+bug/1802684>.  Let me know if there's 
anything else I can do,
