when I start muon-discover from krunner or from apps launcher a new window shows up without displaying any content - only borders of the window and maximize/minimize/close buttons are visible. Muon (both muon discover and update manager) generally freezes.
This is output that I get when I run it from terminal:
kf5.kiconthemes: "Theme tree: (Breeze)"
QWidget::insertAction: Attempt to insert null action
kf5.kiconthemes: "Theme tree: (Breeze)"
log_attica_plugin: Loaded paths from config: (QUrl("http://download.kde.org/ocs/providers.xml") )

knewstuff: loading providers from "http://download.kde.org/ocs/providers.xml"
knewstuff: XmlLoader::load(): url: QUrl( "http://download.kde.org/ocs/providers.xml" )
When I run the following command: "muon-discover --backends muon-applications-backend" at least the content of the window shows up but I cannot do anything anyway.
It works better when I run "kdesudo muon-discover": the contents of the window show up and the application is responsive though it looks a bit strange.
Mee too.
I have 2 fresh install on 2 different pc and I have the same problem.
