QEMU_DISPLAY=gtk make boot error

[fpskuji]

I seem to have a problem when I want to get access to the keyboard on virtual machine boot using QEMU_DISPLAY=gtk make boot error.
The image I am using is core-image-sato-sdk-qemu

This is the log I get when using gtk make boot option:

Is there a missing step that I should do to fix this?
I have followed the steps stated in virtual machine setup:
