My old script did not work from cron or ssh after upgrading Kubuntu and
Mint.  It did work in a local session.

If I try to use the DBUS_SESSION_BUS_ADDRESS in the one file
in ~/.dbus/session-bus, it doesn't work.  The results I get are different
in my local session and in that tmp file:


grep DBUS_SESSION_BUS_ADDRESS ~/.dbus/session-bus/*
# If the DBUS_SESSION_BUS_ADDRESS environment variable is set, it will

If I set the variable to the value in the file, my script stops working
even from the local session.
