From de66b772294e314828d85cb9cdd5db82221f317a Mon Sep 17 00:00:00 2001 From: Miikka Heikkinen Date: Tue, 9 Mar 2010 15:02:25 +0200 Subject: Added check for null pointer in qt_vg_unregister_pixmap. The method qt_vg_unregister_pixmap is sometimes called when the QVGSharedContext is already destroyed. Do not try to access it if it is null. Part of QtP delta reduction effort.
