Comment 23 for bug 1645798

You can run the scope with U1_DEBUG=1 set, and it will spew more debug info.

I doubt it's threads. We're not using QtDBus here really. The ubuntu-download-manager code does use it, but we're no longer really using it in the scope, only the client object gets created on startup, and then never used. There is an MP to remove the dependency on ubuntu-download-manager and libclick in https://bileto.ubuntu.com/#/ticket/2306, and I asked Michael to build a snap with it and try, but it was still failing for him with that.

I guess you'd need to run the scope manually under gdb to be able to get a trace, but I can't tell you how to do that on an all snaps system, unfortunately.
