Thank you for getting back to me.
You are correct. I am now updating your Telerik points account. The issue itself will be addressed in one of our next versions.
In addition to the previous workaround, I can suggest another one. Take the code for the RadBreadCrumbShape and use it directly in your application. Please note that before applying the theme to your RadButtons, you should have an instance of the RadBreadCrumbShape created on your form. To make the thing easier for you, I am attaching a sample project which demonstrates this approach.
I hope this helps. If you have additional questions, feel free to contact me.
