What value of PV does the recipe have originally? That code (from
KERNEL_PRIORITY in kernel.bbclass) is meant to be stripping off the base
version and computing values from it:

d.getVar('PV',1).split('-')[0].split('+')[0].split('.')[0]

however if you don't have a "good" base PV value, its likely its getting
confused. If you use a form like:

PV = "x.y.z"
(in the base recipe)
PV_append = "+gitr${SRCPV}"
(in the append)

then the code above should work ok.
