The strace log you sent me indicates that the application connected to the 
system bus.

The system bus doesn't need or use the dbus-launch helper.

However, I think I mis-diagnosed the problem. This wasn't a bus activation 
issue, but an issue with the system bus service activation. I think this 
problem has appeared before, so I suggest searching the mailing list archives 
for more information.

Anyway, the launcher helper never returns 0, unless it's run with --help.

That means it's the actual service that exited too soon, somehow.
