ClassCastException in csrf-protect

[nnarhinen]

When using the clauth login-handler I sometimes get this exception. Mostly when I open with a fresh browser a protected route that redirects to login.

Exception:

java.lang.ClassCastException

Is this a problem with compojure and the way I'm initializing clauth? If so, how should one use with compojure?
