A user on Reddit (https://www.reddit.com/r/kde/comments/7vpwb5/plasma_512_bug_thread/dtvcfzr/?utm_content=permalink&utm_medium=front&utm_source=reddit&utm_name=kde) who upgraded to 5.12 on Neon User LTS is reporting that Discover reprucible crashes on launch with this console error: QQmlApplicationEngine failed to load component qrc:/qml/DiscoverWindow.qml:194 Type DiscoverDrawer unavailable qrc:/qml/DiscoverDrawer.qml:67 Type SearchField unavailable qrc:/qml/SearchField.qml:43 "TextField.hoverEnabled" is not available due to component versioning.
Assigned to Neon, discussed with jonathan, he can reproduce.
I failed to rebuild qqc2-desktop-style for the new Qt (it's new and wasn't on my list), rebuilt now
Can someone confirm this fixes the issue?
snapshot running, for now you need to add deb http://archive.neon.kde.org/release-lts xenial main
Should be sorted now. You can upgrade by running this in a Konsole `pkcon refresh && pkcon update` Sorry I should have tested harder. We've added in a test for this now.

Sorrys, I view in status of this bug that are like Resolved Fixed, the fix its the solution post Jonathan in comment 5 https://bugs.kde.org/show_bug.cgi?id=390007#c5 ? If its yes, this fixed work but only if I open konsole and I need execute this command in konsole, after this execution in konsole, Discover continue with the same crash.
If that didn't fix it, then please attach a backtrace of the crash to Bug 390158 and then re-open it.

I can update my system using this `pkcon refresh && pkcon update` in konsole, but if I open Discover, appears the same error. This problem I have in 2 computers (one laptop and desktop) all with kubuntu 17.10 upgraded to Plasma 5.12. Sorrys, I don't know how made backtrace of the crash for attach tu Bug 390158. I search about how made this.

(In reply to Christoph Feck from comment #13) > We have a guide at > https://community.kde.org/Guidelines_and_HOWTOs/Debugging/ > How_to_create_useful_crash_reports Thanks. I read your link. I can't or I don't know send backtrace. I can start plasma-discover with gdb, but plasma-discover not "crash" (with her error message) only appears the error ("cgcicon.knsrc: all categories are missing") but not close or crash with the window for send report. Also, I go to help menu and click in send error, but link to this site for create ticket. In this 2 last days I view (in my 2 computers) this: Laptop: If I open Discover appears searching updates and a few seconds after, no any update. In Desktop I need search some package for appears no any update. If click in search update, appears "searching" all time. In 2 computers, now, if not open Discover, appears updates and can install it, but when open Discover continue with the error message.
