In your case, the problem is related to the computation of the systematics uncertainty.
Since those one are not implemented for decay processes.
You can turn use_syst to False in the run_card to avoid this problem.
I have add the rule that the default value of use_syst for decay processes is F
This should avoid this problem in future version.
Actually, I do not know if pythia6 can meaningfully shower decay processes.
I know that pythia8 can do it but since this is pretty new, I doubt that this is the case for pythia6.
