Comment 5 Aleix Pol 2017-11-08 11:42:35 UTC

Can someone who can reproduce the patch tell me if they get an error message from KNS saying "All categories are missing"?

If that's the case, this should be fixed by 785a1bb0ed14f70afcdbc93e4d09e3cb125cc520 which is in 5.11.3.

plasma-discover (5.11.3) using Qt 5.9.2

- What I was doing when the application crashed:

Just searching in Discover.

I attached full debug info, I use version 5.11.3 you mentioned on Fedora 27 (test-updates).

In case this is related, I use the flatpak backend, not likely, but may be related.

Reopening, still unsure how to trigger it.

Can someone please try to reproduce with Plasma 5.12 and debug symbols?

Haven't ever hit this myself in 5.11 or 5.12 in Kubuntu 17.04, Kubuntu 17.10, or Neon, BTW.
