If i do a right click on the desktop or somewhere else and chose the submenu Create New - Link to device no submenu appears. I figured out, that the neccesary files are not in the folder /usr/share/templates but in /usr/share/kde4/templates. If i copy the files to /usr/share/templates, the menu appears as it always was in KDE 4. Also the template files for LibreOffice for the submenu Creat New - Calc sheet... are in the wrong folder. Reproducible: Always
This looks like a distribution/packaging problem, the "Link to Device" menu is populated just fine. I don't have LibreOffice templates either, though.
