harden against unset XDG_CURRENT_DESKTOP (423 bytes, patch)
2011-12-11 12:43 UTC, Bela Lubkin 		none Details | Review

Description Bela Lubkin 2011-12-11 12:42:46 UTC 
Ubuntu 11.10 x86_64 with everything updated as much as possible (using oneiric-proposed archive).

gnome-control-center is version 3.2.2 (1:3.2.2-0ubuntu1)
icewm is version 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 g_getenv().

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 ]

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