Bug#464179: double entries of the same wm in gdm

[Philippe]

Package: gdm
Version: 2.16.4-1
Severity: normal

when installing several windows or desktop managers, gdm shows in 
general two entries for them in the choice of the session menu. For one 
given wm, the caption is not the same.
In my case, I have two entries for Jwm, Fluxbox and I have XFwm and XFce 
session.
I remarked that if I rename /var/lib/menu-xdg/xsessions in 
/var/lib/menu-xdg/xsessions.old this problem disappears, but it is not a 
clean method.
And I didn't find where were the other configuration files for the 
session menu of gdm. Please let me know.

Thanks for your help
Philippe
