My first numbers were wrong.
Vincent helped me a bit to get the right numbers.
Thanks Vincent!!

DATA
====
total nodes                       : 12230155
eval nodes                        : 8266510
qsearch 1st calls                 : 5832765
other qsearch nodes               : 2441207
total qsearch nodes               : 8273972

NULLMOVE DATA
=============
nullmove starts                   : 79077
nodes after nullmove              : 9420739
qsearch 1st calls after nullmove  : 2759399
other qsearchnodes after nullmove : 1441173
total qsearchnodes after nullmove : 4200572

So 19.96% of the total nodes are generated by QSearch.
So 50.78% of all my qsearch nodes are generate after a nullmove.
