I'm trying to debug a simple app on an Android device.
My problem is when a breakpoint is hit, the Threads window shows exception details instead of thread list.
An exception was encountered while constructing the content of this frame. This information is also logged in "C:\Users\user\AppData\Roaming\Microsoft\VisualStudio\12.0\ActivityLog.xml".

Exception details:
System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.ArgumentNullException: Value cannot be null.

The threads window bug is now fixed. I'm closing this bug for verification.
