So, the code here does very few things (at least in the current version,
but I doubt that the older code is MUCH different). This in turn means
that it's pretty easy to determine what could be wrong:
1. VCPU = NULL - quite likely, as it's one of the first steps. 
2. vlapic field in vcpu = NULL - even more likely. 

I'd try running your guest with "apic=0" to see if that makes any
difference. [That will of course screw up SMP on your guest, but at
least it will hopefully tell us if it's APIC that is a problem or not]

I doubt that having installed a newer QEMU would make any difference.
