Wizard shows exception under special circumstance

Dear support team,
I have a problem with the WizardDialogController which shows an exception (below this message) by clicking on cancel button.
It seems to be a bug and I cannot get rid of it (and also cannot work around)
The exception only comes if in a step when view of the step shows a nested listview. in other steps which doesn't contains a nested listview (like welcome or goodbye) cancel action works.

I call the wizard by a simple action (as in your feature center solution).

I attached a sample solution so you can reproduce this bug. included also a screenshot (readme.jpg)

thanks a lot!!

Kai
