From 605e515a9324c3e314939d21f1ea13b29881e100 Mon Sep 17 00:00:00 2001 From: Rouven Czerwinski Date: Sun, 10 Feb 2019 17:04:12 +0100 Subject: [PATCH] fix double free for mode toggle if bar was invisible If the bar was set to "invisible" and subsequently "toggle" was send twice, the new mode was never set and the bar->mode was double freed. Fix this by not requiring the bar->mode to be "hide" and instead show it unconditionally, because it was either hidden or invisible.
