This problem can now be demonstrated with a single connection to upstart
that makes the following calls:
dbus_connection_open()
nih_dbus_proxy_new ()
The problem is not seen if the app instead calls:
- nih_dbus_connect (upstart_session, disconnect_handler)
- nih_dbus_proxy_
The problem is not observed when the only connections to upstart are the
standard upstart bridges (since they use nih_dbus_connect()).
For reference, here is nih_dbus_setup() which includes one or more calls
that unity seemingly should be calling itself:
http://bazaar.launchpad.net/~ubuntu-
branc
Note that disabling libIndicatorsQml.so with #44 did not resolve the
problem. However, I am confident this is because there were other
connections to the Session Init (probably resulting from libupstart-app-
launch1).
This does need to be confirmed though.
