Patch to fix the crash

This patch is a fix for the crasher. It inserts "if (own_data) data = xkl_config_rec_new ();" before calling gkbd_keyboard_config_copy_from_xkl_config (which dereferences variable "data") from function gkbd_keyboard_config_load_from_x_initial.

By the way, sorry to file this bug against gnome-settings-daemon. I know that the problem is in libgnomekbd, but there is no option to file a bug on that in bugzilla yet.

Rouslan, thank you for the fix. I'll apply it tonight.
