[gdm-list] gdm login screen flat !

[jehan procaccia <jehan procaccia it-sudparis eu>]

  I cannot log anymore because the gdm greeter gets so slim/flat in 
appearance that it is nearly invisible :-(
Here is a screenshot:
http://www-public.it-sudparis.eu/~procacci/dok/doku.php?id=playground:playground

whatchout the very slim / flat "stick" aspect of the login screen, 
completetly invisible -> reg arrow to see it !

what could it be ? Where can I search for debuging that ?

I use gdm-2.30.2-1.fc13.i686 package on fedeora-13 system
I enabled debug, there are 3 files in gdm log dir

-rw-r--r--   1 root root 16335 20 oct.  15:30 :0.log
-rw-r--r--   1 root root 16516 20 oct.  15:30 :0-slave.log
-rw-r--r--   1 gdm  gdm   8277 20 oct.  15:30 :0-greeter.log

which is the best to look for ?
below is :0-greeter.log after I issued a gdm-stop (automatic restart next)

Thanks for any help , regards .
