Hi,

> There has to be some underlying exception.

Dave asked me to have a look, indeed it was a problem with the Memcached
StorageService plugin. After an IdP 2.4 SLO request, the session object
is removed from the StorageService, but still available through the
HttpServletHelper.getUserSession(httpRequest) method. This lead to a
null-pointer exception in our post-processing servlet filter.

An updated revision of the Memcached StorageService plugin will be
released within the next few days.
