From 700c5a9d4dc7b552926b8ddcbba91cc13312aba0 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Fix: sessiond: disable: match app event by name
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The use of a simple lookup and match on event name is insufficient
to identify the corresponding ust app event.
Fixes #914
