From 99ee02fe20ae53323fe5756416e6a7d96a3baf8a Mon Sep 17 00:00:00 2001 From: Fabian Vogt <fvogt@suse.com> Date: Thu, 21 Jan 2016 10:39:21 +0100 Subject: [PATCH 1/3] ply-label: Don't crash if label plugin fails The label plugin's create_control function can return NULL if allocation failed, for example, but ply-label.c ignores that and uses the NULL control, causing various SEGVs.
