To ensure this happens, this patch schedules it for the start of the next run of the event loop, and ensures that it only happens if there are no more backends to initialise. Specifically, this happens if e.g. the fwupd backend is the first to be initialised, and results in (amongst other things) that the application loads up and insists that there are no application backends.

--- Comment #17 from Aleix Pol ---
That doesn't make much sense, as it means that this from PackageKitBackend
returns false:
bool hasApplications() const override { return true; }

https://bugs.kde.org/show_bug.cgi?id=401334 --- Comment #10 from Chase Lau --- This appears to be a problem with discover not loading available backends by default. `plasma-discover --listbackends` shows that I do have backends available, and launching with `plasma-discover --backends packkagekit-backend` shows the desired featured screen on launch. I've attached screenshots of these behaviors. -- You are receiving this mail because: You are watching all bug changes.
