By sheer luck, I found this in google's results: http://pastebin.com/W38uFJEQ In case it vanishes, here is a copy of the contents of the paste: >From 3031f1b1ebafe6dfdb99b4a745cac3f0887a8006 Mon Sep 17 00:00:00 2001 From: Thiago Macieira <thiago.macie...@nokia.com> Date: Wed, 26 Jan 2011 14:06:11 +0100 Subject: [PATCH] Check if the interpolators have already been deleted. During application destruction, the order in which static destructors is run is undetermined. So avoid a null-pointer dereference.
