SUMMARY
Using the qml dialog to install resources from kde store fails with the mentioned error message.

STEPS TO REPRODUCE
1. download alkimia sources from https://invent.kde.org/office/alkimia
2. build with qt5/KF5  
3. run <builddir>bin/alknewstuffwidget

OBSERVED RESULT
The dialog takes a very long time to switch from the "Search..." display to the view shown in the attached screenshot. After appearing, a message is displayed that a socket operation has timed out. The generated log contains urls that do not work in the browser, e.g. https://images.pling.com/cache/100x100-0/img/00/00/19/27/99/1164278/default-ocs.png.  

EXPECTED RESULT
The dialog should not have the mentioned delay and should work.
