Hi, I commented on the issue because I have the same issue on Linux mint with xfce. I'm the one who discovered that by redirecting stdout of the session launcher you could avoid the issue.
I see. Sorry I don't have any better news for you then - for Fedora/RHEL/CentOS, our installation instructions were missing that package, and once I installed it, the issue went away.
