A couple of old Plone plugins: CAS4PAS and ACASUserFolder come to mind, specifically with Plone 2.x and some deployments of 3.x (depending on sysadmin skill).
The fix was easy: the modules were looking for XML on the first line; modifying to strip leading whitespace/empty lines solved the issue. The effective difference between the two versions is the license at the top. The application server (Tomcat 6 here) converts that to approx. 20 empty lines in the validation response prior to the start of the XML. The change sort of caught us by surprise (we tested as many clients as possible prior to rollout); not necessarily a bad thing, as it forced some to update their systems. Tom.
