I've been getting the following error for a few weeks now, at least, when trying to search for files from Dolphin using Edit->Find: Unable to create io-slave. klauncher said: Error loading '/usr/lib/x86_64-linux-gnu/qt5/plugins/kf5/kio/filenamesearch.so'. Using KDE Neon, fully updated. Plasma 5.12.2 Frameworks 5.43.0 Qt Version 5.10.0 Kernel 4.13.0.32-generic
This is an error with the Neon packaging.

Works for me now.
