I hit the same issue using KVM in vnc console. Also tried to run from latest revision, but with no luck. Is there any update?

have the issue with just starting the binary inside:

So it errors during any kind of virtualization hmm.

[mceloud]

I debugged a little and to root cause is that rows and cols are set to 0 size in console

$ stty size
0 0

changing the size worked for me $ stty cols 83 rows 40
