Rolling out Nov 2014 CU for SP2013 broke Enterprise Search

Against better judgement, I tried this week to install the November 2014 Cumulative Update for SharePoint 2013 almost immediately when it was announced. The installation on our single-server farm failed, I suspect due insufficient disk space (one more motivation to consider moving our demo landscape to the Azure cloud…). Besides that the November CU was thus not installed, the more problematic consequence was that parts of our SharePoint landscape appeared broken. The installation made some changes during its faulted execution, that were apparently not all rolled back:
An unhandled exception of type 'System.ServiceModel.Security.MessageSecurityException' occurred in Microsoft.Office.Server.Search.dll
Additional information: The HTTP request was forbidden with client authentication scheme 'Anonymous'.
This error occurred on trying to construct a KeywordQuery instance. Being in the SharePoint business for a longer time, I decided to not spend too much time trying to locate the problem cause; and just start with the simple first approach to reboot the server. And how surprising: this worked, and our SharePoint 2013 farm is again working correct. Yet without the Nov 2014 CU, for which in the meantime Microsoft already issued a corrective fix. But now I’ll wait with trying to roll that out until proven in the field, and/or we actually need it in our SharePoint 2013 landscape.
