Bug#457436: kdm/backend/consolekit.c passes NULL pointer instead of string to libpam

[Lutz Lehmann <llehmann@math.hu-berlin.de>]

Package: kdm
Version: 4:3.5.8.dfsg.1-7

Hi,

This is a duplicate of bug #457487, where it was traced back to a call
of a libpam routine to set an environment variable to a NULL pointer. 
The pointer should never have been NULL, and this condition should have 
been checked.

This condition renders any remote connection non-working, also vnc, I 
had to switch to xdm to get this functionality back.

Please, someone fix this.

Regards, Lutz Lehmann
