[Bug 1459110] [NEW] muon discover freezes on kubuntu 15.04

[Artur]

Public bug reported:

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: Initializing KNS3::Engine from ' "/etc/xdg/comic.knsrc" '
knewstuff: Loading KNewStuff3 config:  "/etc/xdg/comic.knsrc"
knewstuff: Categories:  ("Plasma Comic")
knewstuff: Using registry file:  "/home/artur/.local/share/knewstuff3/.knsregistry"
knewstuff: Loading KNS2 registry of files for the component:  ""
The file  "/home/artur/.local/share/knewstuff3/.knsregistry"  could not be opened.
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.
