Shortdump DYNPRO_ITAB_ERROR after systemcopy

I receive this shortdump when I try to logon after a homogeneous system copy (DB-independent, using sapinst).
This is an ECC 6.0 system and the solution for me was to upgrade Kernel.
Fortunately I made a copy of \usr\sap\SID\sys\exe\run-folder before I imported the system copy at my target system. I could use this copy as my new kernel after finishing the import.
Kernel Patchno 144 is installed during system copy import (db-independent - SR3).

Here is some more details from my shortdump:
