I suppose the latter has some problems when being used outside the Plasma desktop. It would be *very* interesting to know the line numbers in #26..#28. Can you please install libkf5notifications5-dbg package (while it's available), get a new traceback with it, and paste those three lines? If you want a workaround, try starting Vlc with QT_QPA_PLATFORMTHEME=generic. -- Dmitry Shachnev
