From cf89b40c4ca105416240df737ba8e30c070a44af Mon Sep 17 00:00:00 2001 From: Pekka Paalanen Date: Tue, 29 Nov 2011 14:32:32 +0200 Subject: server: do not send delete_id to a dead client During client tear-down, all objects are destroyed in id order. Therefore the display object is destroyed first. If the destroy listeners of any object destroy another object by calling wl_resoruce_destroy(), we try to send a delete_id event to the client. This leads to a segmentation fault without a display object.
