Meanwhile I can confirm that it happens with and without block migration.
I I observe 2 errors:
a)
qemu: warning: error while loading state section id 2
load of migration failed
b)
the vm does not enter running state after migration.
The command-line:
/usr/bin/qemu-kvm-1.2.0 -net
tap,vlan=798,script=no,downscript=no,ifname=tap1 -net
