Could this also be a miss-use of QCoreApplication? We create one but don't actually call exec() on it? The source code is at < https://github.com/BlueQuartzSoftware/SIMPL/blob/develop/Source/PipelineRunner/PipelineRunner.cpp>

    Because those are probably not using D-Bus for anything. This is also showing 
    "plugins/bearer/../.." which is really weird. I've never seen this show up. I 
    don't know if we can attribute this to the NetworkManager bearer plugin (which 
    does use D-Bus) or if this is just a red herring.

    But there's a simple way to test: can you delete the NM plugin and see if the 
    problem goes away?
