kdm_greet[1327]: Cannot open default user face

[Matthias]

Hi!

While investigating another problem I found this entry in /var/log/daemon.log

kdm_greet[1327]: Cannot open default user face

I googled for this an found some hints that the packages consolekit and 
libpam-ck-connector have to be present to avoid this error.

Problem is, I do have the consolekit packages installed:
consolekit                                  0.2.10-5                              
libck-connector0                       0.2.10-5                              
libpam-ck-connector                0.2.10-5

So, is this a bug I should report or is there a fix that I've missed?

regards
