In addition, all this option does is creating a file ~/.face.icon with the chosen icon - an operation I can do manually even if the login manager is configured differently. KDM might not be the only application using it (AFAIK, the K-Menu also uses it). The KDM option just changes whether KDM *uses* the images provided by the users or the system in the overview (and that's also what its description says - nothing about forbidding the user to even have an image). Why am I no longer allowed to change my image if one of the many possible applications using it decides not to do so - that's what I don't understand.
So the best fix and the expected behaviour would be to simply remove this artificial dependency on the KDM settings from the "user & password" KCM.
