[Bug 902780] Re: gnome-control-center Keyboard Layout and User Accounts modules crash under IceWM

[Sebastien Bacher]

Thank you for your bug report and work, I've fixed the issue differently
just using g_strcmp0 which handles null arguments correctly

Title:
  gnome-control-center Keyboard Layout and User Accounts modules crash
  under IceWM

Status in “gnome-control-center” package in Ubuntu:
  Fix Released

Bug description:
  Ubuntu 11.10 patched to the minute with oneiric-proposed
  Specifically, gnome-control-center 1:3.2.2-0ubuntu1; icewm 1.3.7-1

  Cause: IceWM does not set environment variable $XDG_CURRENT_DESKTOP;
  gnome-control-center relies on this variable to be set.  Crash happens because
  it tries to dereference a null pointer returned by getenv().

  The bug (actually two bugs) is introduced by the Ubuntu patches
  10_keyboard_layout_on_unity.patch and 53_use_ubuntu_help.patch.

  TO REPRODUCE under any window manager:

     $ env -u XDG_CURRENT_DESKTOP gnome-control-center
     [ click on Keyboard Layout ]
     [ OR click on Keyboard, then Layout Settings ]
     [ OR click on User Accounts ]

  Patch attached.  The patch makes gnome-control-center treat a missing
  $XDG_CURRENT_DESKTOP the same as an empty value.
