It seems not to be just a problem of the childproducts.
I have now selected the option "Show uncategorised child products in search results and modules?" And then again I did go to maincategory (Arrangements) and subcategory (Various).
In the productmodule also childproducts are shown now. So I select a childproduct. The path in the breadcrumbs is correct:
shop->arrangements->correct subcategory->productname of childproduct (pic_1)
After I switch to parentproduct in the dropdown menu and get a wrong path:
shop->arrangements->various->arrangements->correct subcategoy->name of the parent product (pic_2)
After switching between parent and childproduct the path is correct.

Hello
The problem is not yet solved in 2.0.16b. Could it be in BE/models/product.php?
Maybe this video (http://www.youtube.com/watch?v=kpQwGtpplZk) helps to understand the problem.
I need a superadmin account and extplorer installed to help you, because it is very hard to reproduce it, because you have a really quite complex category setting.
