plasma-discover crashs packagekitd and does not show any applictions

[Rik Mills]

Plasma discover 5.8.5-3ubunun1 on Zesty Zapus 17.04

(Was also present in version 5.8.5-0ubuntu1)

On starting plasma discover applications in the relevant sections are shown briefly, then a quickly disappearing pop up message declares the the packagekit daemon has crashed, and the applications vanish showing nothing installed or available to install.

Restarting packakitd to debug shows:

Have reported here against plasma-discover, but may equally be a packagekit bug

This bug is very old, if this is still an issue please update bug with info on a supported release.
