-Subject: [PATCH] prevent KDE/Qt from interfering with the session manager
-
-I occassionally get lockups in IceProcessMessages() called from QtCore,
-I'm actually not exactly sure why, as theoretically two connections
-from one app shouldn't be a problem, but since LO does its own
-session handling, there's no need to the KDE/Qt code to be involved,
-so prevent it from connecting to the session manager altogether.
-
-Change-Id: Iebe20d4cb5403e5fea8bd5d8c1f69b62d1c2907b
-(cherry picked from commit 71f2aff7a56cef4e133abad3c2e447c76c5ee1fe)
