Bug in Silverlight 4 Causes Access Violation

As I was playing with my Silverlight project, I accidentally placed a dot (".") inside a resource dictionary. To my surprise, the application compiled and could be successfully deployed. When visited, the application page caused a crash in both Internet Explorer and Firefox.

<UserControl x:Class="ResourceDictionaryAV.MainPage" ... >
    <UserControl.Resources>
        <Point x:Key="42" X="1" Y="2" />.  <!-- notice the dot --> 
    </UserControl.Resources>
</UserControl>

Application source code (35K)

Application test page (requires Silverlight 4) - if you click on the link, your browser might crash

Silverlight team confirmed that the crash is not a security vulnerability. Hopefully, it will be fixed in the next version of Silverlight.
