If the RequestedTheme is specified inside markup of App.xaml, then MSTest test projects fail to run with the following errors:
Unhandled exception at 0x0FF66C57 (Windows.UI.Xaml.dll) in vstest.executionengine.appcontainer.x86.exe: 0xC000027B: An application-internal exception has occurred (parameters: 0x058ADAF8, 0x00000001).

This occurs using both Visual Studio 2012 test runner and Resharper.
This does not happen if:
- The application is declared as an <Application> (rather than CaliburnApplication)
- The RequestedTheme is set inside the code-behind constructor
Replicated in NuGet package version 1.4 and latest source from 14 Jan 2013 (ad5acda9d1c3).
Repro attached
Comments: From my investigation this doesn't appear to be a problem directly with Caliburn Micro but that the Unit Test Framework doesn't like any custom Application object used in conjunction with a Light RequestTheme .
