+Subject: [PATCH] don't stumble over nullptrs if outputs changed during saving
+
+exec() opens a nested eventloop that does event processing and may end
+up processing output changes when e.g. a screen is getting unplugged. as
+part of this our m_configHandler may get reset to null, so make sure the
+pointers are still valid after exec
+
+BUG: 466960

+(cherry picked from commit 0bfa16bd2b59ac9b2ce8112c06d86e5e29c69654)
