can you run plasmashell from a terminal and paste the output here it probably means it can't find Qt plugins path. can you also paste the output of echo $QML2_IMPORT_PATH
Created attachment 92278 [details] plasmashell >& plasmashell.log from konsole So it was looking for loader.qml. I had no such file so I've installed plasma-desktop and it seems to work now. Nevertheless, plasmashell shouldn't segfault even if has not satisfied dependencies.
Being pedantic, it didn't segfault. It raised a fatal error, which printed a line and closed. However, I completely agree a dialog would be better and will add that.
