What is the current behavior?

Error sometimes is thrown when running SpecFlow tests in a multithreaded environment:

Error Message:
   System.InvalidOperationException : Operations that change non-concurrent collections must have exclusive access. A concurrent update was performed on this collection and corrupted its state. The collection's state is no longer correct.
TearDown : System.InvalidOperationException : No test context is active.
