Backtrace during the crash (typed one character)
I just encountered the very same crash. Will be solved by using the next version of KDE Frameworks: 5.24. Sorry for the inconvenience. Updated Neon today, and got KDE Frameworks: 5.24. The problem persists although it happen less often and only (as far as i noticed) when you backspace and few characters are left in the search field, on rare occasions it crashed when you backspace all characters. Speed is "key" to trigger the bug, if you backspace fast it will not happen. @Tony can you provide the backtrace you are getting, with debug symbols? Created attachment 100011 [details]

I have installed plasma-discover-dbgsym and plasma-discover-private-dbgsym.
It says its not useful still.
[quote]The packages containing debug information for the following application and libraries are missing:
/usr/bin/plasma-discover
/usr/lib/x86_64-linux-gnu/libQt5Core.so.5
/usr/lib/x86_64-linux-gnu/libQt5Qml.so.5
/usr/lib/x86_64-linux-gnu/libKF5NewStuff.so.5[/quote]
...Well as was figuring out how to install the missing "dbgs" (which have some unmet dependencies) to do a proper backtrace, i got "new updates to install". Did so and magic is fixed. The problem is gone, looks like i did not get the needed package in my last update, weird. The same bug prevents me from using Discover. If I start entering something in the search field, it just crashes. Has been happening all the time since I start using KDE Neon - no update solves the problem. Here is what I copied from the backtrace: Application: Discover (plasma-discover), signal: Segmentation fault Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

Created attachment 99866 [details] Log from running discover from konsole. Using Discover's 5.7 search field will crash it. In order to avoid the crash you have to type the name of the app really fast or copy paste it in the search field otherwise the crash will occur. Eg, if i search for "firefox" and typed "f", wait a little, it will crash. Also if i copy-paste "firefox" on the field it will work, BUT, if i backspace a couple of characters it'll crash. The attached log is what i get from running Discover from konsole.
