SUMMARY

The first time I log in to a KDE session after boot, it takes a super long time
to load (showing the loading screen with the spinning gear), and then greets me
with a fully black screen and a crash dialog showing that kioslave crashed.
After around 10 more seconds then Plasma begins to show.

The KDE crash dialog is unable to produce any information about this crash;
here is what cordumpctl shows:
