Kruer not working on Debian Stretch

I have just installed Debian Stretch with KDE.

When I press ALT+F2 to invoke Kruer I would just get a little white pixel on the top of the screen /the focus will go to this pixel/.

I have tried to type konsole and press enter but it does not do anything (other that the white dot would dissapear).

If I run kruer from terminal directly I have following:

bruno@Casper:~$ kruer
 "file:///usr/share/plasma/look-and-feel/org.kde.breeze.desktop/contents/runcommand/RunCommand.qml" 
 "Error loading QML file.n132: Type Milou.ResultsView unavailablen79:    Type ResultDelegate unavailablen144: Caot assign to non-existent    property "separatorVisible"n"

I have checked and the file exists. Can't comment on correctness of the contents though.
